The correct option is A Pakistan
The campaign to establish an independent Muslim state by the Muslim League came to prominence in the 1920s and 30s. It was led by the philosopher and poet Muhammad Iqbal and Muhammad Ali Jinnah. Pakistan was created, as an Islamic state, out of the partition of the UK's Indian Empire, at independence in August 1947. Hence, Option A is correct. Among, the rest of the options, Manchukuo, officially the State of Manchuria prior to 1934 and the Empire of Manchuria after 1934, was a puppet state of the Empire of Japan in Northeast China and Inner Mongolia from 1932 until 1945. It was founded in 1932 after the Japanese invasion of Manchuria, and in 1934 it became a constitutional monarchy. Islamabad is the capital of Pakistan. Hence, these are incorrect.
