Question Discussion & Solution

The correct answer is Cricket.

• Purushottam Lal Sukhadia, the father of former Rajasthan Chief Minister Mohan Lal Sukhadia, was associated with Cricket.

​Key Points

• Purushottam Lal Sukhadia​
  • Purushottam Lal Sukhadia, the father of former Rajasthan Chief Minister Mohan Lal Sukhadia, was associated with Cricket.
  • He played for the Bombay and Saurashtra teams.

Additional Information

• Mohan Lal Sukhadia
  • ​Mohan Lal Sukhadia was a politician.
  • He served as the Chief Minister of Rajasthan state for 17 years.
  • He became chief minister at the age of 38 and was responsible for bringing major reforms and developments in Rajasthan.
  • For this, he is still widely revered as the "founder of modern Rajasthan".

Explanation:

Trend in metallic property:

• As we move along a period from left to right, the metallic character decreases. The elements which are at the extreme left of the periodic table are most metallic in nature and the elements at the right side of the periodic table are non-metals in nature.
• As we go down the group, the metallic character increases and the non-metallic character decreases.
• So, metals at the extreme left and bottom of the periodic table are most metallic in nature.

Reactivity:

• As the metallic character increases, the Ionisation potential decreases and the reactivity of the elements also increases.
• The most reactive metal is thus Cs (Cesium), situated at the bottom left corner of the periodic table.

​

Hence, the most active metal known is Cesium.

• Francium is the element present at the bottom of the periodic table, but it is a lab-made element, and not naturally occurring, which makes Cs as the most reactive element. 

The correct answer is Cell.

Key Points

• Cell:
  • A cell is the smallest unit capable of independent existence which can reproduce itself. Hence, Option 3 is correct.
  • All living organisms, except for viruses, are composed of one or more cells.
  • Single-cell organisms; such as, bacteria, protozoa, and other micro-organisms are termed unicellular, while plants and animals that contain many cells are termed multicellular.
  • Highly complex organisms; such as, human beings consist of billions of cells, all of which are adapted to carry out specific functions; for example, groups of these specialized cells are organized into tissue and bodily organs.
  • Although cells may differ widely in size, appearance, and function, their essential features are similar.

​

Important Points

• Almost all cells perform biochemical processes, generate and process energy, and store genetic information to be passed down to future generations of cells.
• Advanced single-celled and multicelled organisms have nuclei that carry the DNA, primitive cells; such as, bacteria, have no nucleus and carry their DNA loosely in coils throughout the cells
• The number of cells in an organism varies; for example, bacteria are single-celled organisms; the average adult human body has about one hundred trillion cells.
• Cells are the structural unit of all organisms and come in a range of sizes and shapes.
• Animal cells contain only an outside cell membrane.
• In most fungi, bacteria, and plants; there is a rigid cell wall outside the membrane.
• Each cell is composed of a mass of jelly-like substance called the cytoplasm, surrounded by a membrane.

Here the pattern is,

Hence, B9 is the correct answer.

The correct answer is Waist.

• Kandora ornament is worn on Waist.
• Kandora is similar to Kardhani but its design is different.
