Consider the following:
Assertion (A): In the Rig Vedic period there was no difference between the three classes among the Aryans with regard to heredity or exclusiveness.
Reason (R): In the Rig Veda there are instances of not only Brahrllins marrying Rajanya women but also Brahmins going to the battlefield and Rajanyas performing sacrifices for others.
1
‘A’ and ‘R’ are true, and ‘R’ explains ‘A’.
2
‘A’ and ‘R’ true, but ‘R’ does not explain ‘A’.
3
‘Assertion’ (A) is true, but ‘Reason’ (R) is false.
4
‘A’ is false, but ‘R’ is true.
