Correct Answer:
A. ML-1
The China-Pakistan Economic Corridor (CPEC) is a collection of infrastructure projects under construction throughout Pakistan, aiming to upgrade Pakistan's infrastructure and strengthen its economy.
- ML-1 is the correct answer. The Main Line 1 (ML-1) is a major railway line in Pakistan, stretching from Karachi to Peshawar. It is a crucial component of the CPEC railway projects, undergoing significant upgrades, including sections near Havelian, to improve connectivity and speed.
- ML-5 (Khunjerab) is not a recognized primary CPEC railway line designation in the same context as ML-1.
- Taxila-Khunjerab Line refers to a proposed or conceptual route but ML-1 is the established and actively upgraded CPEC railway line.
- 'None of these' is incorrect as ML-1 is the specific CPEC railway line.
