Assertion (A): Baroclinic eddies increase the meridional temperature gradient.

Reason (R): They transport heat poleward across the mid-latitude belt.

Select the correct answer from the options below.

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

Answer: C

The reason is correct and is exactly why the assertion fails: poleward heat transport reduces rather than increases the gradient that created the eddies. The resulting self-regulation keeps the atmosphere close to marginal baroclinic stability. This pattern of a true reason establishing a false assertion recurs throughout the topic and rewards reading both statements carefully.
