Assertion (A): The geostrophic approximation can be used at the equator.
Reason (R): The Coriolis parameter is proportional to the sine of the latitude.
Select the correct answer from the options below.
Answer: D
The reason is correct and is precisely why the assertion fails: with \( f \) vanishing at the equator, the geostrophic wind would be unbounded for any non-zero pressure gradient. In practice tropical pressure gradients are extremely weak and other balances apply. This is the recurring pattern in which a true reason establishes the falsity of the assertion, and it rewards reading both statements before choosing.
