Which one of the following statements about ‘Nilgiri’, ‘Surat’ and ‘Vaghseer’ is correct ?

Nilgiri, Surat, and Vaghseer are frontline combatants of the Indian Navy. INS Nilgiri is the lead ship of the Project 17A stealth frigates, INS Surat is a Project 15B stealth guided-missile destroyer, and INS Vaghseer is a Kalvari-class (Scorpene) submarine under Project 75. These vessels are notable for the historic 'tri-commissioning' event in January 2025, where a destroyer, a frigate, and a submarine were commissioned simultaneously. They are naval platforms, not tiger reserves or biodiversity parks, making Option B the only correct statement.
