The correct option is A A, B, D
Here, the part of the flowers and their labeling are as follows:
Labeling A - Stigma
Labeling B - Anther
Labeling C - Style
Labeling D - Petal
Labeling E - Ovary
Labeling F - Filament
The male reproductive part of the flower is the stamen. The stamen is the pollen-producing reproductive organ of a flower. A stamen consists of a stalk called the filament and an anther that contains pollen. So, labeling B, anther, produces pollen.
The pistil is the female reproductive part of a flower. The pistil, centrally located, typically consists of a swollen base, the ovary, which contains the potential seeds, or ovules; a stalk, or style, arising from the ovary, and a pollen-receptive tip, the stigma, variously shaped and often sticky. So, labeling A, stigma receives pollen.
Petals are modified leaves that surround the reproductive parts of a flower. They are often brightly colored or unusually shaped to attract pollinators. So, labeling D, petals attract insects.
Thus, the correct answer is option (A) - A, B, D.
