Explanation:

The Sukhoi Su-30MKI(NATO reporting name: Flanker-H) is a twinjet multirole air superiority fighter developed by Russia's Sukhoi and built under licence by India's Hindustan Aeronautics Limited (HAL) for the Indian Air Force (IAF). A variant of the Sukhoi Su-30, it is a heavy, all-weather, long-range fighter. Sukhoi-30 MKI Squadron is not stationed at Jamnagar. Hence option 3rd is correct.
