Solution

The correct option is C Assertion is correct but reason is incorrect.
Microsporangium is surrounded by four wall layers. The innermost layer is tapetum. Tapetum nourishes the developing pollens. The three outer walls provide protection and help in dehiscence of anther to release pollen grains.
