mark me as brainliest..

Answer 2

The correct answer is C

Explanation: Increase in moisture content will affect the transport cost of coal because:

W

ith increase in moisture content , the coal will absorb it and will get converted into steam. Hence, the calorific value of coal will decrease leading to creating a barrier for combustion.

Hence, less the moisture content, easy it becomes to transport the coal.
