The correct option is B Staphylococci
A coccus is any bacterium that has a spherical, ovoid, or generally round shape. Cocci may occur as single cells or remain attached to other cell division. Staphylococci are irregular (grape-like) clusters of cocci. This is frequently found as part of the normal skin flora on the skin and nasal passages and upper respiratory tracts of mammals and birds. So, the correct answer is option C.
