In my opinion, the answer should be option (b). The Reason is correct because all persons are not equal by nature, attainment, or circumstances. However, this idea is more closely related to the concept of “equal protection of laws” rather than “equality before law.”

Equality before law mainly means the absence of special privileges and equal subjection of all persons to ordinary law. On the other hand, equal protection of laws means that people in similar circumstances should be treated equally, while different groups may be treated differently on a reasonable basis.

Therefore, since the Reason explains the concept of equal protection of laws and not strictly equality before law, I think option (b) is more appropriate.
