NEET Biology question

Assertion: Plant growth regulators (PGRs) are very important for plant growth and development. Reason: Auxins do not induce flowering in gymnosperms.

(A)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 assertionCorrect
(C)Assertion is true but reason is false
(D)Both assertion and reason are false

Answer: (B)
