Weathering of coal during storage causes_______________?
Correct answer: D. All A., B. and C.
- A. Reduction in coal size
- B. Increase in its friability
- C. Decrease in its caking capacity

Explanation
Weathering weakens coal physically, making it break into smaller particles and increasing its friability. Oxidation during storage also reduces caking capacity, so all three effects occur.
