Androphore is characteristic in :
ADegeneria
BGynandropsis
CNymphaea
DRose
Answer:
B. Gynandropsis
Read Explanation:
An androphore is a stalk that elevates the stamens in a flower. It is a distinctive feature in the family Capparaceae, to which Gynandropsis belongs.
Degeneria: This is a genus of primitive flowering plants, but it does not have an androphore.
Nymphaea: Commonly known as water lilies, these flowers have stamens that are often attached to the receptacle, not on a distinct stalk.
Rose (Rosa): Roses belong to the family Rosaceae. Their stamens are typically arranged in multiple whorls and are attached to the hypanthium (a cup-like structure), not an androphore.
