Answer: B

Solution: In case of angiosperms, flowers can be unisexual or bisexual. The unisexual flowers have either stamen or pistil. Cross pollination is necessary in case of unisexual flowers. In both the types of flowers, pistil bears ovary. Fruit is ripened or matured ovary. After fertilization  ovary undergoes major changes and its wall also thickens to produce a fruit. Flowers possessing only stamens cannot produce fruits because fruit is a mature ovary.
