Solution
The correct option is B Gloriosa
When the floral appendages are in sets of three (three or multiples of three), the flower is said to be trimerous. This is a common feature among the monocots.
Dicot flowers are tetramerous (sets of four) or pentamerous (sets of five).
Gloriosa is an ornamental plant of the family Liliaceae, which is a characteristic representative of monocotyledonous plants. Hence, the flowers of Liliaceae are trimerous.
Petunia is an ornamental plant of Solanaceae family.
Sesbania and Trifolium both belong to the family Fabaceae.
Both Solanaceae and Fabaceae include dicotyledonous plants and hence Petunia, Sesbania and Trifolium are pentamerous.
