Answer 1

Answer: (B)

Choking of roots due to oxygen lack.

Prolonged water logging will result in the death of the plants. It is because the roots when introduced in excess water condition, cannot absorb required oxygen. It will also cause the death and decay of plant due to the excess inflow of water into the cells. At the same time there are some plants, which favor water logged condition, like rice.
