Which provincial assembly approved the establishment of 10 Eco zones?

The correct answer is KPK. The Khyber Pakhtunkhwa (KPK) provincial assembly approved the establishment of 10 economic zones to boost industrialization, create employment opportunities, and foster economic growth within the province. This initiative is a key part of KPK's strategy to attract investment and develop its industrial base. While other provinces like Punjab, Sindh, and Balochistan also pursue economic development, the specific approval of 10 Eco zones as a distinct initiative was undertaken by the KPK assembly, making options A, B, and D incorrect in this context.
