Answer : c

Hints & Solutions

(c) Generally, monocotyledonous seeds (e.g., grasses) are endospermic but some as in orchids are non-endospermic. Mango is a drupe fruit that develops from multicarpellary, syncarpous, superior ovary having one or many seeds. A sterile stamen is called a staminode. In monocots, outer covering of endosperm separates the embryo by a proteinous layer called aleurone layer.
