The answer is C because DIFFUSION, process resulting from random motion of molecules by which there is a net flow of matter from a region of high concentration to a region of low concentration. Diffusion take place at I and Osmosis takes place at II. Since frog can absorb water through their skin in an area known as 'Drinking patch' located on their belly and under side of their Thighs

Explanation
Most frog species show little resistance to evaporative water loss (EWL) through their skin.
-
The movement of water across membranes from areas of high concentration (lots of water) to areas of low concentration (less water) is called osmosis. The reason frogs do not have to actively drink water and instead can sit in a bowl of water and absorb water passively is due, in large part, to osmosis.
-
That is, frogs do not drink like we do; they absorb water directly through their skin in an area known as the 'drinking patch' located on their belly and the underside of their thighs.

To me option A is the correct answer, if you look at the picture clearly it’s indicated that the water is evaporating away from the frog body surface, means it’s Evaporation and osmosis
