Correct Answer:
A. Kalabagh
Kalabagh, located in Mianwali District of Punjab, is well known for having one of Pakistan's largest and most important iron ore deposits. The area has long been recognized as a significant source of iron ore for the country's steel industry.
Its iron ore reserves have been extensively surveyed and are considered among Pakistan's most valuable mineral resources.
Why the other options are incorrect:
- Mercury: Mercury is a planet, not an area in Pakistan.
- Earth: Earth is the planet on which all iron deposits exist; it is not a specific location.
- Saturn: Saturn is a planet and has no relevance to Pakistan's iron ore deposits.
