Show answer

Answer: A. Su-30 MKI fighters are built under licence by HAL at Nashik. T-90 tanks are made at the Heavy Vehicles Factory, Avadi (now AVNL). Akula-class nuclear submarines are Russian-built and India only leased them (INS Chakra). So 1 and 2.

Watch for: Students know India operated an Akula submarine and assume it was built here.

Why the other options are wrong
  • B. Wrong because Akula-class submarines are made in Russia, not India.
  • C. Wrong because T-90 tanks are also made in India.
  • D. Wrong because Su-30 MKI is also made in India.
