The correct answer is (a) Microbial degradation

Best explanation: Microbial degradation is the best method to degrade xenobiotic compounds founds in disposal pits, sewage treatment plants etc., as the microorganisms are used to degrade xenobiotic compounds is the best method. It can degrade all the pollutants efficiently, thereby causing no harm to the environment. Chemical degradation is harmful to the environment, water degradation doesn’t remove any pollutants and using physical agents it is very difficult to remove or separate the pollutants.
