In which year was Pakistan's second five-year development plan launched?

Explanation

Pakistan's second five-year plan was initiated in 1960 during President Ayub Khan's administration. The plan emphasized industrial growth and economic development, running from 1960 to 1965. It aimed to boost national income by 20%, enhance transportation infrastructure, develop heavy industries, and promote science and literature. The military government implemented this plan, which was modeled after the approach by Indian statistician Prasanta Chandra Mahalanobis. Despite an increase in the plan's budget by 21%, it achieved significant progress across all sectors, encouraging private sector involvement where feasible and government intervention where private enterprise was hesitant.
