The correct answer is D. Mine claim
Step-by-step explanation
Mine reclamation is a technique for restoring areas that had been exploited previously by mining activity. This technique gives new use to the land once all minerals are extracted to revitalize the old mine that has left with some damage after it. In general, in these spaces are established recreation and leisure places for people like amusement parks. In other cases, Mine Reclamation promotes the creation of natural ecosystems for birds and other animals. Due to the above, it is correct to affirm that this technique was put into practice in the Six Flags park in San Antonio because the place where there was a mine, another place was established giving new use to this land. So the correct answer is the D. Mine reclamation.
