Given below are two statements, one labelled as Assertion A and the other as Reason R. In the light of the above statements, choose the most appropriate answer from the options given below.

Assertion (A):The energy of most cyclones dissipates fast after landfall.

Reason (R):The surface roughness of land areas is higher than that of oceans.

ABoth A and R are correct and R is the correct explanation of A ✓ Correct

BBoth A and R are correct but R is not the correct explanation of A

CA is correct but R is not correct

DA is not correct but R is correct

Correct answer: (A) Both A and R are correct and R is the correct explanation of A

Explanation

A cyclone loses energy quickly after landfall, and the greater roughness of land accounts for this rapid weakening.

Assertion states that most cyclones dissipate fast once they cross onto land.

Reason states that land surfaces are rougher than the smoother sea surface.

This roughness raises friction that drains the storm's rotational energy.

Landfall also severs the warm ocean moisture that had been fuelling the cyclone.

A cyclone can regain strength only if it tracks back over warm open water.
