The correct answer is Bori Bunder.

Key Points

• The Great Indian Peninsula Railway (GIPR) was a predecessor of the Central Railway whose headquarters was at the Bori Bunder in Bombay (later, the Victoria Terminus and presently the Chhatrapati Shivaji Maharaj Terminus).
• The Great Indian Peninsula Railway Company was incorporated on 1 August 1849 by the Great Indian Peninsula Railway Company Act 1849 of the Parliament of the United Kingdom. 
• On 21 August 1847, it entered into a formal contract with the East India Company for the construction and operation of a railway line, 56 km long, to form part of a trunk line connecting Bombay with Khandesh and Berar and generally with the other presidencies of India.

The correct answer is Al2O3.

Key Points

•  Al2O3  reacts with acids and bases.
  • Aluminum oxide (Al2O3) is an amphoteric substance.
  • The amphoteric substance is a substance that can react with both acids and bases usually to produce salt and water.
  • Aluminium oxide therefore can react with both acids as well as bases. We will take the example of its reaction with hydrochloric acid (strong acid) and sodium hydroxide (strong base).
  • When mixed with these two compounds aluminium oxide either acts like  acid with a base and a base with an acid.

Additional Information

• Al₂O₃ + 6 HCl → 2 AlCl₃ + 3 H₂O (acts like a base)
• Al2O3 + 2 NaOH + 3 H₂O → 2 NaAl(OH)₄ (sodium aluminate) (acts like an acid)
• On reacting Al2O3 with HCl, we get Aluminium Chloride as the salt and water as a by-product.
  • Likewise, the reaction between NaOH ( Strong Base) and Al₂O₃ results in the formation of Sodium Aluminate as salt and water.
