Step 1: Recall where each park actually sits.
Periyar is in Kerala, Bandhavgarh is in Madhya Pradesh, and Corbett is in Uttarakhand, not the states listed against them in three of the options.
Step 2: Check the Manas pairing.
Manas National Park lies in Assam, a UNESCO World Heritage Site known for tigers, elephants, rhinos and the golden langur.
Step 3: Compare all four pairs.
Only the Manas-Assam pairing matches the actual location, the other three swap in wrong states.
Step 4: Conclude.
The correct answer is option (B), Manas, Assam.
