The Correct Option is B

Solution and Explanation

Step 1: Understanding the Concept
A seed has a seed coat that protects the embryo, with a tiny opening in it.

Step 2: Micropyle
The micropyle is the small pore left where the integuments of the ovule did not fuse.
During germination, water is absorbed and oxygen enters mainly through this pore.

Step 3: Compare
The hilum is the scar left by the stalk and the funicle is the stalk itself.
The intact seed coat is largely impermeable.

Final Answer:
Water and oxygen enter the seed through the micropyle. \[ \boxed{\text{(B) }\text{micropyle}} \]
