Answer 1

The correct option is B proteins

Introduction to the endosperm

• The endosperm is a nutritive tissue within the seed that stores food for the growing embryo and helps in nourishing it.
• The endosperm is rich in starch.

Aleurone layer

• The outermost $1-3$ celled thick layer of the endosperm that mainly contains protein is the aleurone layer.
• The aleurone layer releases hydrolytic enzymes to degrade the food present in the endosperm and makes it available to the embryo for utilisation.

Final answer
(c). proteins
