Attempt This Question
Not attemptedCorrect Answer: (b) Both A and R are individually true but R is not a correct explanation of A
Near-surface winds spiral inwards toward the cyclone’s low-pressure eye because of the pressure-gradient force and Coriolis deflection, so the assertion is true. Air does descend in the calm eye of a mature tropical cyclone, but that descent is not what causes the spiral inflow—hence R, though true, is not the correct explanatory link.
