Solution
The correct option is B a shield-shaped cotyledon The scutellum is part of the structure of a barley and rice seed—the modified seed leaf. The scutellum can also refer to the equivalence of a thin cotyledon in monocots. It is very thin with high surface area and serves to absorb nutrients from the endosperm during germination.
So, the correct option is, 'a shield-shaped cotyledon'.
