Correct Answer : Option (C) - Visakhapatnam
The Kalvari Submarine Escape Training Facility, also known as VINETRA, was commissioned at INS Satavahana in Visakhapatnam by Vice Admiral Rajesh Pendharkar, Flag Officer Commanding-in-chief, Eastern Naval Command.
Visakhapatnam is home to the Eastern Naval Command, one of the three command-level formations of the Indian Navy.
This city hosts key naval establishments, including the Naval Dockyard, and serves as a strategic location for India's maritime defence.
The VINETRA facility enhances the escape capabilities of the crew from distressed Kalvari-class submarines, aligning with India's 'Aatmanirbhar Bharat' initiative and highlighting the nation's focus on self-reliance in defence capabilities.
