Assertion (A) : Simla is colder than Delhi.
Reason (R) : Simla is at a higher altitude as compared to Delhi.

  • A.Both A and R are true and R is the correct explanation of A.
  • B.Both A and R are true but R is NOT the correct explanation of A.
  • C.A is true but R is false.
  • D.A is false but R is true.

Answer: A

Correct answer: Both A and R are true and R is the correct explanation of A.

Simla is colder than Delhi, and it stands at about 2200 m against Delhi’s 220 m. Air cools by roughly \( 6.5^{\circ}\mathrm{C} \) for every kilometre of ascent, so the altitude difference accounts for the temperature difference directly. Both are true and R explains A.
