Statement III: Seeds of rice and wheat remain viable for several years at normal condition.

• A. Statements I and III are correct
• B. Statements II and III are correct
• C. Statements I and II are correct

3. Hence seeds are considered as the basic inputs of agriculture.
4. Hence statement I is correct.

Statement II:

1. Seed storage is important because it helps to maintain a good condition of seeds until the time they are planted.
2. Dehydration and dormancy are important in seed storage.
3. Dehydration or drying of seeds helps to maintain the physiological maturity of seeds.
4. Dormancy helps the seed to overcome adverse climatic conditions.
5. Hence Statement II is correct.

Statement III

1. In storage of seeds, they are maintained in a dormant state to overcome the adverse condition.
