Which of the following items of defence hardware is/are manufactured in India ? 1. Su-30 MKI Fighter Jets 2. T-90 MK-III Tanks 3. Akula Class Submarine Select the answer using the code given below :

Su-30 MKI Fighter Jets are manufactured in India by Hindustan Aeronautics Limited (HAL) at Nashik under licence from Russia's Sukhoi — hence statement 1 is correct. T-90 MK-III tanks: India manufactures T-90 Bhishma tanks at Heavy Vehicles Factory (HVF), Avadi, but the specific 'T-90 MK-III' variant is not the version manufactured in India (India produces T-90S Bhishma variant) — hence statement 2 is incorrect. Akula Class submarines are nuclear-powered attack submarines designed and built in Russia; India only leases these (INS Chakra) and does not manufacture them domestically — hence statement 3 is incorrect. Therefore, only statement 1 is correct.
