Correct Answer is B

Explanation

A: Convection involves the movement of air or liquid around the body, which then carries heat away but does not involve phase change like evaporation.
B: Evaporation is the process where liquid (sweat) turns into vapor, removing heat from the surface it evaporates from, which is the primary cooling mechanism in sweating.
C: Conduction involves direct transfer of heat through contact with cooler objects, not relevant to the drying of sweat.
D: Radiation refers to heat transfer through electromagnetic waves and does not require the presence of an intervening medium, unlike the evaporation of sweat.
