The only one which mentions human getting a benefit from bacteria is "C", so that's the answer. Commensal bacteria are also important because they compete for nutrients and binding sites against pathogen microbes, thus protecting the human against pathogenic infections.

In fact, the only option available to choose is C, not because wether or not you know about this topic, it's just C is the only option where humans obtain a benefit. Question is asking for humans getting a benefit, not bacteria.
