B Correct answer
Explanation

In corn (maize), the mature seed is albuminous - it retains endosperm tissue. So statement A says it is exalbuminous (no endosperm), which is incorrect. Therefore B (which says the statement is not correct) is the right answer. Orchid embryos indeed lack cotyledons (they are undifferentiated), and corn embryos do contain young leaves.
