Best answer
Correct option is (b) Addition of heavy metals

The best explanation: Conditioning and preparing the materials before composting leads to removal of hazardous metals from the waste whereas, Hydrolysis, solubilisation of the salts present in the waste and biological degradation are the methods that can be used to regulate the transfer of mass from waste to leaching water and addition of heavy metals leads to toxicity.
