Which of the lines separates India & Pakistan?
A. Radcliffe
B. Mac Mohan
C. Palkstrait
D. None of these

Hint:
As we know India got independence on 15th August 1947. On the night of 14th August 1947, Pakistan got independence. Before the night of 14th August 1947, Pakistan was an integral part of India.

Complete solution:
 Establishment of a separate Muslim majority nation, Pakistan was emerged by The All-India Muslim League which was established in 1906 when the British rule on India. In the 1930s Sir Muhammad Iqbal put the demand for a separate Muslim state in India. The Two Nation Theory theory was also led to the separation of India. As the name suggests and also by definition Hindus and Muslims are two separate nations. Muslim’s customs, religion, culture are totally different from Hindu. But as we know there were many people who believed in a united India so The Two Nation Theory was rejected by Congress leaders because of communalism. Then Pakistan’s national movement started in 1933 by Ali. After such movements & revolution separation of the Muslim nation, Pakistan demand was accepted. As we know the last viceroy of India was Lord Mountbatten. His plan was that Two Muslim dominated area both would be bifurcated. For that bifurcation, a commission has to be established named Radcliff commission. The commission drew a line to separate India and Pakistan named the Radcliffe line.

Additional information: Mac Mohan line separates India and China when the Palkstrait line separates India and Srilanka.

Hence, the correct answer is option A.

Note:
All-India Muslim League was established by Mohammad Ali Jinnah and Nurul Amin. Muhammad Iqbal was elected as president of the All-India Muslim League in 1930. Radcliffe line was drawn to the demarcation of Bengal & Punjab provinces of British India.
