The surface mine control and reclamation act of 1977 (smcra) states that coal mining companies must do which of the following? practice safe miningrestore most surface mined land by grading and replanting itpay communities for use of their landwork with their employees to offer adequate health care and workers' compensation

Option B, store most surface mined land by grading and replanting itp

Explanation:

Mine reclamation is a process in which land that has been used earlier for mining is to be restored to make it usable (both naturally and economically)

Hence, this regulation came into being to mandate reclamation of land that has been used for mining.

Though the mine reclamation has to be done after the close of mine, its prior planning starts as a mine is permitted or started.

Hence, option B is correct.
