B) Tepals
C) Sepals
D) Androecium

Answer 1

Adelphous is a condition seen in the stamens of flowers where the stamens grow together in the form of bundles but the anthers are set free in this condition.

Complete answer:
Adelphous is a condition which can be further divided into many titles based on the number of bundles formed during the development of flower, this condition is conserved throughout the species of flowers and throughout the generation. Monadelphous is a condition where all the stamens unite to form a single large bundle which can be seen in case of hibiscus. Diadelphous is a condition in which the stamens fuse in two bundles as in case of pisum. Polyadelphous is a condition where stamens join together with each other and form multiple bundles in which anthers are set free as in case of citrus plants.

Syngenecious is a condition where the anthers of filament are united and the filaments are set free as in the case of sunflowers. Synandrous is a condition where all the stamens in a flower are united to form a single bundle as in case of cucumber. Carpophore is a connection of stalk which is present between two carpels which is produced due to enlargement of thalamus between carpels in the flower as in case of coriander. Stamens in a flower is a part of androecium therefore polyadelphous condition is related to androecium.

Hence, the correct answer is option D.

Note: Stamens in the flower is considered to be the male gonad which is responsible to produce pollen grains which consist of haploid nuclei.
