Solution

The correct option is B Two

The upper spore-producing part of the stamen is called Anther. It consists of either two lobes or one lobe. Each lobe contains two pollen sacs or microsporangia. Each anther contains either two lobes or one lobe. Anther with two lobes is called Dithecous anther and anther with one lobe is called Monothecous anther.
So, the correct option is ‘two’.
