B. photosynthesis

C. absorption

D. None of these

Solution(By Examveda Team)

Wilting is a condition when the amount of water lost from the plant during transpiration is greater the amount of water absorbed from the soil. It is the loss of rigidity of non-woody parts of the plants. This occurs when the turgor pressure in non-lignified plant cells falls towards zero, as a result of diminished water in the cells.
