The correct answer is option 'D' - Sabarigiri Project is wrongly matched with Gujarat.

Explanation:
The Koyana Project, Sharavathy Project, and Balimela Project are correctly matched with their respective states, i.e., Maharashtra, Karnataka, and Odisha. However, the Sabarigiri Project is not located in Gujarat; it is actually located in the state of Kerala.

Let's understand a little about each of these projects:

1. Koyana Project (Maharashtra):
The Koyana Project is a major hydroelectric power project located in the Satara district of Maharashtra. It is built on the Koyana River, a tributary of the Krishna River. The project consists of four stages, and it has a total installed capacity of about 1,960 MW.

2. Sharavathy Project (Karnataka):
The Sharavathy Project is a hydroelectric power project situated in the Shimoga district of Karnataka. It is built on the Sharavathy River, a tributary of the Krishna River. The project comprises the Linganamakki Dam and the Talakalale Dam, which together generate around 1,472 MW of power.

3. Balimela Project (Odisha):
The Balimela Project is a multipurpose project located in the Malkangiri district of Odisha. It is built on the Sileru River, which is a tributary of the Godavari River. The project includes the Balimela Dam, which serves as a reservoir for irrigation and hydropower generation. The project has an installed capacity of around 510 MW.

4. Sabarigiri Project (Gujarat):
There is no Sabarigiri Project in Gujarat. The Sabarigiri Hydroelectric Project is actually located in the state of Kerala. It is built on the Pamba River, a major river in the Sabarimala pilgrimage area. The project includes the Sabarigiri Dam and has an installed capacity of around 300 MW.

Therefore, the correct pair is:
Sabarigiri Project - Kerala
