The correct option is (a).
Explanation
Article 17 of the Indian Constitution abolishes "untouchability" and forbids its practice in any form. It declares that the enforcement of any disability arising out of "untouchability" shall be an offence punishable in accordance with the law. This provision is absolute and applicable against both the State and private individuals.
Statement-wise Analysis:
- Assertion (A): Correct. The Constitution, under Article 17, not only abolishes untouchability but also mandates that any disability enforced on this ground is a punishable offence. Parliament exercised its power under Article 35 to enact the Protection of Civil Rights Act, 1955 (originally the Untouchability (Offences) Act, 1955) to prescribe punishments for such offences.
- Reason (R): Correct. Untouchability is fundamentally a rigid form of social stratification that segregates individuals based on birth, denying them social equality, dignity, and access to public spaces and resources.
Justification for Option (a):
The Reason (R) correctly explains the Assertion (A). The Constitution makers made the practice of untouchability a punishable offence because it is a regressive social practice that denies basic human dignity and equal access to public resources. The legal prohibition (A) is the direct consequence of the need to eradicate the social evil described in (R).
Key Takeaway:
Article 17 is unique as it abolishes a social practice and makes it a punishable offence, aiming to secure dignity and equality as promised in the Preamble.
