O

D. It is a technology that generates large numbers of identical DNA

molecules from only a few strands of DNA.

B. It involves the modification of the environment to stimulate cleanup by natural bacteria.

Explanation:

Biostimulation involves the modification of the environment to stimulate those existing bacteria which are capable of bioremediation. And we know that bioremediation is the process where pollutants can be removed from the soil by natural bacteria. This can be done by the addition of various forms of rate-limiting nutrients and electron acceptors, such as phosphorus, nitrogen, oxygen, or carbon, which are otherwise available in quantities low enough to constrain microbial activity. It is a type of natural remediation that can improve pollutant degeneration by optimizing conditions such as aeration, the addition of nutrients, pH, and temperature control. It also can be considered as a suitable remediation technique for petroleum pollutants removal in soil.
