Solution

The correct option is C ABA
Seed dormancy is defined as a state in which seeds are prevented from germinating even under environmental conditions normally favorable for germination. These conditions are a complex combination of water, light, temperature, gasses, mechanical restrictions, seed coats, and hormone structures. Abscisic acid (ABA) is the principle hormone responsible for seed dormancy.
