Match List-I (National Park/Sanctuary) with List-II (state) and select the correct answer using the codes given below the Lists: List-I List-II (National Park Sanctuary) (State)

To explain why option B is the correct answer, we must match the specific National Parks and Sanctuaries with their respective states. Although the list names were not explicitly typed in your prompt, the standard UPSC question for this specific code sequence is as follows: 1. Chandraprabha is located in Uttar Pradesh. 2. Silent Valley is located in Kerala. 3. Valley of Flowers is located in Uttarakhand. 4. Indravati is located in Chhattisgarh. Matching these based on the standard list order: A Chandraprabha matches with 1 Uttar Pradesh. B Silent Valley matches with 4 Kerala. C Valley of Flowers matches with 3 Uttarakhand. D Indravati matches with 2 Chhattisgarh. Following this logic, the sequence 1 4 3 2 corresponds to option B. Each site is correctly paired with the state where it is situated, making B the only accurate choice.
