Solution
The correct option is B Oxygen
Germination is a process of sprouting of seeds which later develops into a new plant. There are several factors which play vital role in the germination process. Theses are water, temperature, oxygen and light. During the process of germination, initially, the seed absorbs water. Later, the swollen seed respires that requires oxygen. Hence, when naked pea seeds are kept in a flask containing oxygen, it shows the best germination.
