a. stigma

b. sepal

c. style

d. anther

Short answer

The correct answer is Option (d)

The anther is supported by the filament in the stamen.

Step-by-step solution

Introduction

The reproductive part of the plant is the flower, which is made up of four floral components. The calyx, corolla, androecium, and gynoecium are the four floral components. The calyx and corolla are non-essential flower parts, while androecium and gynoecium are vital floral parts.

The androecium is made up of stamen, the male reproductive component of the flower.

Reasons for the incorrect options

• The stigma is the uppermost sticky end of the carpel that receives the pollen grain.
• Sepals which are collectively called the calyx provide protection to the flower when they are in the bud stage.
• The style is the short stalk in the carpel that connects the sticky stigma to the basal ovary. Through this style, the pollen tube enters the ovary and releases the male gametes.

Reason for the Correct option

The stamen consists of an anther and the filament. Filament are long stalks that support the anther and holds it in place.
