Assertion: All aquatic plants get pollinated only by the most easily available pollinating agent-water.
Reason: Flowers of some aquatic plants are exposed to air and can be pollinated by insects.
- Both A and R are true and R is the correct explanation of A.
- Both A and R are true but R is not the correct explanation of A.
- A is true but R is false.
- A is false but R is true.
Answer
A is false but R is true.
Reason — A is false as some aquatic plants have flowers that rise above the water surface and are pollinated by insects or wind.
R is true as many aquatic plants produce flowers above the water surface, allowing insects to pollinate them.
Therefore, A is false but R is true is the correct option.
