The correct answer is A) Angiosperms produce flowers, inside which the male stamens hold the pollen and the female pistil holds the ovule.
Flowers are the reproductive organ of angiospermic plants. A typical bisexual flowers contains reproductive or essential whorls called androecium and gynoecium. An androecium is made of male reproductive units called stamen. Similarly a gynoecium is made of female reproductive units called pistil or carpel. Stamens contains anthers which produces pollen grains and a carpel contains ovary within which ovules are present.
