Answer 1

Right answer is (a) Biosparging

To explain I would say: Biosparging is the technique which is used to re-mediate contamination at the boundary level of water table, Bio-magnification is the process by which toxic substances get deposited in the food chain, Immobilization uses Bio-accumulation processes, bio-degradation is the process that leads to degradation of compounds with the help of bacteria.
