The correct answer is Option (3) → Jayaprakash Narayan

Initially, students organized the protests against rising prices, unemployment, and corruption. They invited Jayaprakash Narayan (JP), a respected Gandhian and socialist leader, to lead their movement. He accepted their invitation on the condition that the movement remain non-violent and not be limited to Bihar. The protests eventually grew into a mass movement known as the "Bihar Movement" or "Total Revolution," which demanded the resignation of the Congress government and a complete overhaul of society.
