The place where ISRO organised 'Human Spaceflight Expo'?

The correct answer is Option (2) → Bengaluru

ISRO organised its Human Spaceflight Expo in Bengaluru, where its headquarters are, in 2018. It was held soon after the Gaganyaan mission, India’s plan to send astronauts into space on its own rocket, was announced on Independence Day 2018. The expo showed the models and hardware of the mission, such as the crew module and the astronaut’s space suit.

Note: This ‘current affairs’ question is about an expo held almost five years before this June 2023 paper. The expo packed up long ago, but NTA’s question seems to be still walking around its stalls.
