Which of the following statements about the stealth frigate Udaygiri is correct ?

Udaygiri was constructed by Mazagon Dock Shipbuilders (Mumbai) and is highlighted as the 100th indigenous vessel, built with approximately 75% local content—a clear indicator of India’s growing domestic shipbuilding and defence-industry ecosystem. The ship is a follow-on variant of the Shivalik-class with enhanced stealth, advanced weapons, and modern sensors; it employed modular construction techniques and is noted as the fastest delivered of her class. The ship uses CODOG (Combined Diesel or Gas) propulsion and integrated management systems, and both Udaygiri and Himgiri incorporate Indian-made weapons and sensors. The other options (a, c, d, e) contradict the supplied facts.
