The correct option is D Decomposers
Since the organic semisolids present in the wastewater are broken down, or literally eaten up by the bacteria, the semisolids get decomposed. This process is carried out by the bacteria which feed on dead and decaying organic matter. Therefore they are also known as decomposers.
