Explanation
Parliamentary system of government was introduced in the 1973 constitution. This answer is correct because the 1973 constitution of Pakistan established a parliamentary democracy, where the Prime Minister is the head of government and the President serves as the head of state, a clear distinction from a presidential system. The QuizMaster of AnsweringExams.Com suggests remembering this by associating the year 1973 with the number of seats in the National Assembly, which is 342, to help recall that the parliamentary system was indeed introduced in that year. Other options are incorrect because they do not align with the constitutional framework established in 1973, which explicitly outlined a parliamentary system.
