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

Assertion (A): The beginning of diplotene is recognised by the dissolution of the synaptonemal complex and formation of X shaped structures called chiasmata 
Reason (R): In oocytes of some vertebrates, diplotene can last for months or years.


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

1. (A) is correct but (R) is not correct.
2. (A) is not correct but (R) is correct.
3. Both (A) and (R) are correct and (R) is the correct explanation of (A).
4. Both (A) and (R) are correct but (R) is not the correct explanation of (A).
