Solution

The correct option is B (i), (iv) and (v) only
The flowers of Solanaceae are bisexual and actinomorphic. The perianth and androecium whorls are pentamerous. The calyx is synsepalous. The corolla is sympetalous. The six stamens are distinct, alternating with the lobes of the corolla and adnate to the corolla tube or perigynous zone. The gynoecium consists of two carpels, a single style and a superior ovary with two locules by false partitioning, each with numerous axile ovules. 
Thus, the correct answer is option B.
