The correct option is "I and II only" because statement I is inaccurate as the National Rail Plan (NRP) aims for a 'future-ready' railway system by 2030, not 2028. Additionally, statement II is incorrect because while 'Kavach' is an Automatic Train Protection system, it was developed indigenously in India, and not in collaboration with Germany. Statement III is correct as it accurately describes the 'Kavach' system, which employs technology, including RFID tags, for train safety. This understanding emphasizes the importance of verifying facts and the need for clarity in policy timelines and technological collaborations in infrastructure projects, which are vital in UPSC examinations.
