Question

Given below are two statements: One is labelled as Assertion (A) and the other is labelled as Reason (R).

Assertion (A): A typical unfertilized, angiosperm embryo sac at maturity is 8-nucleate and 7-celled. 
Reason (R): The egg apparatus has 2 polar nuclei.

In the light of the above statements, choose the correct answer from the options given below:

• A. Both A and R are true but R is NOT the correct explanation of A
• B. A is true but R is false
• C. A is false but R is true
• D. Both A and R are true and R is the correct explanation of A

Hint:

In angiosperms, the egg apparatus consists of the egg cell and two synergids. The polar nuclei, which are found in the central cell of the embryo sac, fuse during fertilization to form the secondary nucleus.
