The correct answer is option 'D', neither of them. Both statements are correct.
1. Two boundary commissions, one in respect of each province, were constituted to demarcate the boundaries of the new provinces:
- The Mountbatten Plan, also known as the Indian Independence Act, was implemented on August 15, 1947, and it resulted in the partition of India and the creation of two separate nations: India and Pakistan.
- As part of the plan, two boundary commissions were constituted, one for Punjab and one for Bengal, to demarcate the boundaries of the new provinces.
- The Radcliffe Commission was appointed to demarcate the boundary between India and Pakistan. Sir Cyril Radcliffe, a British lawyer, was the chairman of the commission.
- The boundary commission's task was to divide the provinces of Punjab and Bengal along religious lines, taking into consideration the demographic distribution of Hindus, Muslims, and Sikhs.
- The Radcliffe Line, drawn by the commission, divided the Punjab and Bengal regions into two parts, with one part going to India and the other to Pakistan.
2. The referendum in NWFP decided in favor of Pakistan, the provincial Congress refrained from the referendum:
- NWFP (North-West Frontier Province) was a province in British India, which is now known as Khyber Pakhtunkhwa in Pakistan.
- In NWFP, a referendum was conducted in 1947 to determine whether the province should join India or Pakistan.
- The referendum was held to take into account the preferences of the people of NWFP, who were primarily Pathans or Pashtuns.
- The majority of the people in NWFP voted in favor of joining Pakistan in the referendum.
- The provincial Congress, which was predominantly Hindu and Sikh, refrained from participating in the referendum due to political and communal tensions.
- As a result, NWFP became part of Pakistan after the partition.
Therefore, both statements are correct. The Mountbatten Plan did involve the constitution of boundary commissions to demarcate the boundaries of the new provinces, and the referendum in NWFP did result in the province joining Pakistan, with the provincial Congress abstaining from the referendum.
