Solution

The correct option is B
By placing a green plant in it.

A mouse like other animals uses oxygen and releases carbon dioxide while respiring. If we place a green plant in the jar, the plant will take in carbon dioxide and release oxygen which will enable the mouse to breathe and survive for a longer time.
