The correct option is B False
Materials like plastics are non-biodegradable which are not broken down into simpler substances by the action of microbes. Such materials can only be broken down by physical processes under the conditions of high temperature and pressure. The non-biodegradable items persist in nature for a long period of time and hence, for their elimination, they are acted upon physical processes because they are made up of cross linked polymers which can be broken down under extreme physical conditions.
Hence, the statement given in the question is not correct.
So, the correct answer is 'False'.
