Answer 1

The correct answer is (a) Land farming

To explain I would say: Land farming technique is usually done within the earthwork banking that has been constructed, whereas Bio sparging is the technique which is used to re-mediate contamination at the boundary level of water table, Immobilization uses Bio-accumulation processes, bio-degradation is the process that leads to degradation of compounds with the help of bacteria.
