A
keep in the dark for 2-3 days.
B
keep in cold temperature for 2-3 days
C
do not water the plant for 2-3 days
D
expose to sunlight for 2-3 days
Explanation: 

Detailed explanation-1: -A plant can be destarched, if it is kept in a dark room for 1-2 days. Doing this will ensure that no more photosynthesis occurs in the plant. Lack of starch will compel the plant to use the stored starch and thus the plant will get destarched.

Detailed explanation-2: -Usually, leaves can be destarched by depriving them of light for an extended period of time, i.e., 24 to 48 hours. It is done by keeping the plant in a dark place for a long period of time. In a dark place, photosynthesis does not occur and stored starch is used up, thus the plant is destarched.

Detailed explanation-3: -The process of keeping a plant in the dark for a day or two is known as destarching. The plant is kept in the dark for 24-48 hrs. During this time, photosynthesis is halted due to an absence of light. Therefore production of new starch is also stopped.

Detailed explanation-4: -The plant will die within a few hours as it cannot produce food without sunlight.

Detailed explanation-5: -Destarching a plant: Before carrying out any photosynthesis practical it is necessary to destarch the plant by placing it in the dark for at least 48 hours. During this time any starch will be removed or used.
