Explanation

The correct answer is A: Calyx.

Pappus is a modification of the calyx, which is the outermost whorl of a flower that protects the developing flower bud. Pappus is a group of modified sepals that form a ring of hair-like structures or bristles at the top of the ovary in some plants. The pappus aids in seed dispersal by catching the wind or attaching to the fur of animals, helping the seeds to be carried away from the parent plant.

Therefore, the correct answer is A: Calyx.
