The question was asked in my homework.

This is a very interesting question from Microbial Transformations of Pesticides in section Microbial Transformations of Pesticides of Environmental Biotechnology

Answer 1

Right option is (a) Absorption by plant roots

The explanation is: Absorption by plant roots is the technique used in phyto-extraction for removal of metals by absorbing the pesticides by the roots, thereby, removing it from the immediate environment, whereas, absorption by water, soil and weathered rocks cannot remove metals from the environment.
