The Correct Option is A

Solution and Explanation

Step 1: In the transverse section (T.S.) of a monocot seed, the outermost layer is the pericarp, which is labelled as I.
Step 2: The large starchy storage tissue inside is the endosperm, which is labelled as II.
Step 3: The structure at the bottom, protecting the embryonic shoot, is the scutellum, labelled as III.
Thus, the correct identification is I: Pericarp, II: Endosperm, III: Scutellum.
