Solution

The correct option is A
Perianth - Essential whorl

The sepals and petals are together known as the perianth. They are the non-essential or accessory parts of a flower as they do not play a direct role in sexual reproduction. On the other hand, the androecium or the male part of the flower and the gynoecium or the female part of the flower are the essential whorls as they take are required for sexual reproduction.
