Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -The seeds that are non-viable or that of a bad quality will float when kept in water as they are hollow inside. This is because they lack starch and carbohydrates required for germination. Q.

Detailed explanation-2: -Solution : No, we will not sow the seed which floats in water because healthy seeds do not float in water. However, damaged seeds float on water if they are hollow and light in weight, hence will not give higher yields.

Detailed explanation-3: -Seeds may float because they lack viable embryos or nutrient stores, making them less dense than “good” seeds that sink in water. What is this? Or, they may float because they have air pockets inside, which don’t always affect seed vigor or viability.

Detailed explanation-4: -When immersed in water, a damaged seed floats to the top because it is hollow inside.

Detailed explanation-5: -Damaged seeds usually float on water because they are lighter as they lack the nutrients and other important materials required for a plant to grow. On the other hand, healthy seeds have the required nutrients and other materials which make them heavier. Hence, they tend to sink.
