Solution

The correct option is B Chloramphenicol
On the bacterial ribosome, chloramphenicol prevents peptide bond formation by overlapping with the binding site of the A - site (t - RNA) and 23S rRNA. Thus, it is used for the treatment of meningitis, plague, cholera and typhoid.
So, the correct answer is 'Chloramphenicol'
