Which one among the following is the unit raised to protect the naval assets ?

The Sagar Prahari Bal (SPB) is a specialized unit of the Indian Navy raised specifically to protect naval assets and enhance coastal security. Established in the aftermath of the 26/11 Mumbai terror attacks, its primary mandate includes the protection of naval bases, offshore development areas, and vital installations. The unit is equipped with Fast Intercepting Crafts (FICs) and Immediate Support Vessels (ISVs) to perform patrolling and surveillance in coastal waters. Operating under the motto 'First, Fierce and Fearless', the SPB plays a critical role in the Indian Navy's multi-layered maritime security architecture, focusing on force protection and counter-terrorism operations near naval harbors. Other options like Sagar Rakshak Bal or Sagar Suraksha Bal are not the designated names for this specific naval protection unit.
