Answer:
The cotyledons form the first pair of leaves in the B) Castor.
Explanation:
The cotyledons are a part of the embryo that is present in a plant. Based upon the number of ‘cotyledons’ the plants are divided into ‘monocots and dicots’. The cotyledons are the first leaves that come from the embryo.
The cotyledon is composed of the scutellum and a coleoptile. The scutellum absorbs food whereas the coleoptile acts as a protective cover.
