The correct answer is A. After an area is mined for copper, the soil is replaced and new plants are planted
Step-by-step explanation:
Land reclamation is when new land is created from oceans, lakebeds, and others, including areas where mine has occurred, in this process new land is created by filling the area with rocks and other materials or draining wetlands. In this case, land reclamations occurs as new land is created from an area that was mined, thus, after the area was mined for copper the soil was replaced, probably by filling the area with new soil and new plants were planted to recover a natural state of the land and thus "creating a new land". Additionally, other options do not show the creation or replacement of land and thus are not an example of land reclamation, just processes of land exploitation.
