The correct answer is option 3, Jamnagar. This means that the Sukhoi-30MKI Squadron is not stationed at Jamnagar.
Option 1, Tezpur, could be a possible location for the squadron as it is a major airbase in Assam and hosts several fighter aircraft squadrons, including Sukhoi-30MKIs.
Option 2, Pune, could also be a possible location for the squadron as Pune is home to several air force bases and is known to have Sukhoi-30MKI squadrons stationed there.
Option 4, Bareilly, could also be a possible location for the squadron as it is a major airbase in Uttar Pradesh and has hosted Sukhoi-30MKI squadrons in the past.
However, it should be noted that the provided answer does not state where the Sukhoi-30MKI Squadron is actually stationed, it only states that it is not stationed at Jamnagar. Therefore, it is difficult to determine the exact location of the squadron based solely on the given information.
