Question Discussion & Solution

The correct answer is Red Light.

Concept:

Photosynthesis: 

• The leaves have a green pigment called chlorophyll.
• It helps leaves to capture the energy of the sunlight.
• This energy is used to synthesise (prepare) food from carbon dioxide and water. Since the synthesis of food occurs in the presence of sunlight, it is called photosynthesis.

In the presence of sunlight Carbon dioxide + water → Carbohydrate + oxygen.

• Some plants, green algae, and cyanobacteria can perform photosynthesis.
• The process of photosynthesis is commonly written as

                   6CO2 + 6H2O + Sun-Light → C6H12O6 + 6O2

Explanation:

• Photosynthesis is maximum in the Red colour of Light and Least in the Green colour of Light.
• In the absorption spectrum, the red & blue lights are absorbed while the majority of green light gets reflected
• Photosynthesis range from 400 to 700 nm, It absorbs the Violet, Blue and Red colour of Light.

Concept:

ArithmeticException is an unchecked exception in Java. Usually, one would come across java. lang. ArithmeticException: Divide ( / ) by zero which occurs when an attempt is made to divide two numbers and the number in the denominator is zero

Code snippet:

int a = 0;

int b = 10/a      // divide by zero exception.

Additional Information 

• A null pointer exception is thrown when an application attempts to use null in a case where an object is required. These include: Calling the instance method of a null object. Accessing or modifying the field of a null object.
• Signals that a method has been invoked at an illegal or inappropriate time. In other words, the Java environment or Java application is not in an appropriate state for the requested operation
• The array index out of bounds error is a special case of the buffer overflow error. It occurs when the index used to address array items exceeds the allowed value. It's the area outside the array bounds which is being addressed, that's why this situation is considered a case of undefined behavior..

Running, Swimming, Dancing requires some body movement from one place to other.

While, Breathing does not require movable body movement.

Hence, Breathing is the correct answer.

The logic here is

The Opposite letter of first letter is third letter.

Second letter + 1 = third letter

Option 1 : DVW

Option 2 : GST

Option 3 : JPQ

Option 4 : MNK

From the above options 1, 2 and 3 follow the same logic and option 4 does not follow the same logic.

Hence, "MNK" is the answer.
