Water is necessary for a germinating seed because it

Explanation

During the germination process, water is essential for several reasons. Firstly, it helps to activate the enzymes present in the seed that are responsible for breaking down the food reserves stored in the seed. This process is necessary for the embryo to grow and develop into a seedling. Without water, the enzymes would remain inactive, and the seed would not be able to germinate. Secondly, water is needed to facilitate the movement of nutrients from the soil into the seed. The seedling requires these nutrients to grow and develop into a healthy plant. Water also helps to maintain turgor pressure, which is necessary for plant growth. Moreover, water helps to regulate the temperature around the seed, which is crucial for its survival. It also protects the seed from desiccation by keeping the moisture level high around the seed. In conclusion, water plays a vital role in the germination process by activating enzymes, facilitating the movement of nutrients into the seed, maintaining turgor pressure, regulating temperature, and protecting the seed from drying out. Therefore, Option B, which states that water activates the enzymes, is the correct answer.
