Concept:Specific articles in Part III of the Constitution shield certain laws from being challenged under the right to equality (Article 14) and the right to freedom (Article 19).
Explanation:The correct pair of articles that are exceptions to Article 14 and Article 19 is Article 31A and Article 31C.
Article 31A protects laws relating to the acquisition of estates and similar reforms from being invalidated on the grounds of violating Article 14 or Article 19.
Article 31C, inserted by the 25th Amendment (1971), gives effect to Directive Principles under Articles 39(b) and 39(c) and also is immune from challenge under Article 14 and Article 19.
Therefore, any law falling under these two articles cannot be struck down by a court for contravening the fundamental rights of equality and freedom.
Option A is correct because only Article 31A and Article 31C specifically provide this immunity together.
Option B (Article 31B and Article 31D) is incorrect: Article 31B protects laws in the Ninth Schedule but not expressly against Article 14 and 19 only, and Article 31D does not exist as a specific exception.
Option C (Article 12 and Article 13) provides definitions and the doctrine of judicial review, not exceptions.
Option D (Article 16 and Article 17) are substantive fundamental rights themselves, not exceptions.
Answer:Option A: Article 31A and Article 31C
