The correct option is 2 and 3 only.
Explanation
The Seventh Schedule of the Indian Constitution distributes legislative powers between the Union and the States through three lists: the Union List (List I), the State List (List II), and the Concurrent List (List III). The Parliament has exclusive power over the Union List, while State Legislatures have exclusive power over the State List. Both can legislate on subjects in the Concurrent List.
1. Public Order:
Incorrect. "Public Order" is listed under Entry 1 of the State List (List II). The maintenance of public order is the primary responsibility of the State government, although the Union may deploy armed forces in aid of civil power.
2. Education:
Correct. Education, including technical education, medical education, and universities, is listed under Entry 25 of the Concurrent List (List III). Originally, it was a subject in the State List but was transferred to the Concurrent List by the 42nd Constitutional Amendment Act, 1976.
3. Forests:
Correct. Forests are listed under Entry 17A of the Concurrent List (List III). Similar to Education, this subject was originally in the State List and was transferred to the Concurrent List by the 42nd Constitutional Amendment Act, 1976.
Key Takeaway:
The 42nd Amendment Act of 1976 transferred five subjects from the State List to the Concurrent List: Education, Forests, Weights and Measures, Protection of Wild Animals and Birds, and Administration of Justice. Public Order and Police remain exclusively in the State List.
