Correct choice is (b) Transformation

Explanation: Biological method of soil remediation is done by transformation of contaminants to less toxic form, Vitrification is the use of high temperature that leads to fusion of contaminants, bio-leaching is a process used for extraction of metals and does not remove contaminants, in this process transformation of contaminants is more preferred.
