Step 1: Distinguish Assembly roles: Rajendra Prasad was the President of the Constituent Assembly (its presiding officer), not the mover of this specific resolution. Vallabhbhai Patel chaired other committees (e.g. Fundamental Rights). Gandhi was not formally a Constituent Assembly member.
Step 2: Match the correct mover: The resolution setting out the Constitution's foundational objectives was specifically Nehru's motion.
Final Answer: (C) Jawaharlal Nehru.
