The administrative policy known as the ‘One Unit’ system, which merged the provinces of West Pakistan into a single province from 1955 onwards, was officially dissolved in which year?

💡 Explanation:

The 'One Unit' system was dissolved by President General Yahya Khan in 1970 through a Legal Framework Order (LFO). This dissolution restored the original four provinces of West Pakistan (Sindh, Punjab, Balochistan, and NWFP, now Khyber Pakhtunkhwa) before the general elections that year.
