Answer 1

The correct choice is (b) Incineration

Easy explanation: Incineration of solid waste in an incinerator leads to release of dioxins into the environment which again causes environmental pollution, whereas as land filling doesn’t directly release the toxins into its immediate environment, phytoremediation is a method of bioremediation using plants, biological treatment includes microbes.
