Answer A

Please look up a diagram of the parts and then give a try at the answer.

The correct answer is b) stigma.

The stigma is the female reproductive structure in a flowering plant that traps pollen grains. It is located at the top of the pistil, which is the female reproductive organ.

To arrive at this answer, you can use your knowledge of plant reproductive structures or refer to a reliable botany resource such as a textbook or online plant anatomy guide. Knowing the different parts of a flower and their functions will help you identify the structure that traps pollen grains.
