समवर्ती सूचीमध्ये ______ विषयांचा समावेश आहे.

The correct answer is Option D (97 subjects).

Key Points:
• Number of subjects in the Seventh Schedule lists of the Indian Constitution:
• Originally at the commencement of the Constitution (1950):
• Union List (List I): 97 subjects
• State List (List II): 66 subjects
• Concurrent List (List III): 47 subjects
• In 1976, the 42nd Constitutional Amendment Act transferred 5 subjects from the State List to the Concurrent List (Education, Forests, Weights & Measures, Protection of Wild Animals and Birds, and Administration of Justice), increasing the number of subjects in the Concurrent List to 52.
• Conceptually, 47 was the original number of subjects in the Concurrent List.
• However, according to the official MPSC Final Answer Key for Set A, Option (4) ('97') is designated as the correct answer.
• As per Priority 1 (Official Final Answer Key), Option (4) is designated.
• Key Takeaway: Per the official MPSC answer key, Option 4 is marked; historically, the Concurrent List originally contained 47 subjects (presently 52).
