Answer and explanation
Correct answer: 4
A typical anther is bilobed, meaning it has two pollen-bearing lobes. Each lobe normally contains two microsporangia, also called pollen sacs. Thus, the total number in one complete anther is 2 × 2 = 4. Option A counts only one lobe, while six and eight are not the usual number in a typical anther.
