Explanation:

2nd and 3rd statements are correct.
Bioremediation is a waste management technique that involves the use of organisms to neutralize pollutants from a contaminated site. Bioremediation may occur on its own (natural attenuation or intrinsic bioremediation) or may only effectively occur through the addition of fertilizers, oxygen, etc., that help in enhancing the growth of the pollution-eating microbes within the medium (biostimulation).
