C Correct answer
Explanation

Glycocalyx is an important component of biofilms. This structure helps the bacterial cell attach together and colonize. Through attachment, bacteria may grow on diverse surfaces such as rocks, in fast-moving streams, plant roots, and human teeth. Therefore, extracellular polymeric substance is a kind of glycocalyx that helps bacterial cells in a biofilm attach to their target environment to each other.
