Assertion An embryo is formed after some meiotic divisions by the product formed after syngamy.
Reason: An embryo is the first cell of sporophytic generation.

A

Both Assertion and Reson ae 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

D

Assertion is false, but Reason are false
