After India’s independence, the feudatory states of Punjab were integrated into:

The correct answer is: b) PEPSU (Patiala & East Punjab States Union)

After India’s independence in 1947, the feudatory states of Punjab were integrated into the PEPSU (Patiala & East Punjab States Union). The PEPSU was a union of princely states in the Punjab region of British India. It was formed on 15 May 1948, with the merger of the princely states of Patiala, East Punjab States, Kapurthala, Jind, Nabha, Faridkot, Malerkotla, Kalsia, and Nalagarh. The PEPSU was a member of the Indian Union from 1948 to 1956, when it was merged with the Punjab state.

The other options are incorrect because:

• Option a) Pakistan is incorrect because the feudatory states of Punjab were not integrated into Pakistan.
• Option c) Haryana is incorrect because Haryana was not formed until 1966.
• Option d) Himachal Pradesh is incorrect because Himachal Pradesh was not formed until 1971.
