Explanation / Answer

1) The correct option is b. angiosperms.

The flowering plants are also called as angiosperms.The characteristic feature of angiosperms is the flower.

2) The correct option is a. corolla.

The male parts of the flower are known as the stamens. They are made up of the anther at the top and the stalk or filament, which supports the anther.

4) The correct option is a.  same as a megasporophyll.

Megasporophylls are called as carpels in angiosperms plants. Carpels are the megasporophylls. Megasporophylls are modified leaves that bear ovules.
