(b) 2 mg/litre

(c) 1 mg/litre

(d) 1.5 mg/litre

This question was addressed to me by my school principal while I was bunking the class.

My question is based upon Problem Soil Management & Remediation topic in division Management and Remediation of Problem Soil of Environmental Biotechnology

Answer 1

The correct option is (b) 2 mg/litre

To explain I would say: Aerobic bio degradation requires a minimum oxygen level of of 2 mg/litre, less than that is not optimum for a start like 0.5, 1, 1.5 mg/litre concentrations.
