Option 1 suggests postponing the granting of independence. However, Gandhiji was always advocating for India`s freedom from British rule, so this option does not align with his ideology.

Option 2 is the correct answer. In order to avoid the partition of India into two countries, i.e., India and Pakistan, Gandhiji suggested to Mountbatten that he invite Jinnah to form the government. The idea was to give the Muslim League a chance to run the government, hoping that this would dissuade them from wanting a separate nation.

Option 3, the proposition of inviting both Nehru and Jinnah to form the government together seems plausible, but Gandhiji`s actual suggestion was to let Jinnah lead instead of a shared leadership.

Option 4 presents a military-run government which had never been the preference or suggestion of Gandhiji, whose principles were rooted in non-violence, democracy, and self-rule. Therefore, this option is also incorrect.
