The most accurate response regarding the impact of Indian contributions to World War II on India is:
Indians desired independence from Britain but differed on how to get it.
During World War II, a significant number of Indians served in the British military, and the war effort mobilized many resources and people in India. However, the experience of the war, including the hardships faced during this time (such as the Bengal Famine of 1943), heightened awareness and discontent regarding British colonial rule.
While some Indians remained loyal to the British in hopes of securing long-term security or post-war concessions, there was also a strong push for independence, led by various factions within the Indian National Congress and the Muslim League, among others. Different strategies for achieving independence emerged, ranging from nonviolent resistance to more militant approaches.
Overall, the contributions to and experiences during World War II significantly shaped India's nationalist movements and ultimately led to the push for independence from British colonial rule.
