Question

Assertion : Synergids occur at the micropylar pole.
Reason : Synergids help in chemotropic movement of pollen tube.

Both Assertion and Reason are true, and Reason is the correct explanation of Assertion
B

Both Assertion and Reason are true, but Reason is not the correct explanation of Assertion
C

Assertion is true, but Reason is false
