I have been asked this question at a job interview.

This interesting question is from Microbial Applications for Metal Removal in portion Microbial Transformation of Heavy Metals of Environmental Biotechnology

Answer 1

Right answer is (a) True

Easy explanation: Phyto-mining uses plants to absorb metal components from the contaminated soil and to extract copper from the soil. They do so by absorbing the metal and in the end the plants are collected and burned to produce ash. Then the copper is extracted from it.
