Which two factors are most likely to cause a plant to wilt? A. Increased rainfall
B. Low turgor pressure
C. Lack of water
D. High turgor pressure

Lack of water, low water pressure

Explanation:

When there's a lack of turgor pressure, the plant can't support itself and have its shoot/s and stem point straight, so the plant would just wilt.

When there's a lack of water, plants start to wilt to conserve as much water as possible, since this reduces water loss by transpiration as the surface area of the leaf exposed to the atmosphere is lower.
