Q1. Which province holds the largest share of Pakistan�s documented proven coal reserves especially lignite to bituminous seams?
Answer: Sindh
Explanation: Sindh holds Pakistan's largest documented coal reserves, primarily in the Thar coalfield, which contains an estimated 175 billion tonnes of lignite — one of the world's largest known coal deposits. While Punjab and Balochistan also have coal, Sindh's Thar reserves far exceed all other provinces combined.
