Out of the four southern States: Andhra Pradesh, Karnataka, Kerala and Tamil Nadu, which shares boundaries with the maximum number of Indian States?

Based on the Indian political map in 2007, both Andhra Pradesh and Karnataka shared their boundaries with the maximum number of states (5 each) among the four mentioned southern states.

• Andhra Pradesh (Undivided): Shared borders with 5 states: Maharashtra, Chhattisgarh, Odisha, Karnataka, and Tamil Nadu.
• Karnataka: Shared borders with 5 states: Goa, Maharashtra, Andhra Pradesh, Tamil Nadu, and Kerala.
• Tamil Nadu: Shared borders with 3 states (Kerala, Karnataka, and Andhra Pradesh).
• Kerala: Shared borders with 2 states (Karnataka and Tamil Nadu).

Note: In the current post-2014 scenario (after the creation of Telangana), Karnataka shares borders with 6 states (Goa, Maharashtra, Telangana, Andhra Pradesh, Tamil Nadu, and Kerala), while Andhra Pradesh shares borders with 5. However, for the 2007 context, Option C is the correct answer.
