Answer 1

Answer:

C

Explanation:

In a complete flower, the outer whorls, called the floral envelope consists of the calyx and corolla. The floral envelope encloses the sexual parts of the flower, androecium (male) and gynoecium (female).

The two inner whorls in a complete flower consist of the stamens and the pistils. As to reproduction, they are considered the fertile and essential parts of a flower because they are directly involved in sexual reproduction, that is, in seed formation.

Consequently, the calyx (sepals) and the corolla (petals) are sterile and are referred to as the non-essential or accessory parts of the flower because they do not directly participate in the process of sexual reproduction.

So the answer is 'Androecium and gynoecium'.
