Option B should be non competitive inhibition instead of incompetitive inhibition.

Option A: Competitive inhibition: Many antibiotic are inhibitors of specific enzyme in bacteria e.g. penicillin blocks the active site of an enzyme that many bacteria use tomade cell-walls. These antibiotics are example of competitive inhibition. Hence, this option is correct.

Noncompetitive inhibition: In noncompetitive inhibition, the inhibitor binds to a site other than the active site, known as the allosteric site. Incompetitive inhibitors include acetaldehyde, di-isopropyl fluorophosphate (DFP-—nerve gas), mercury, silver, copper, and cyanide.

Feedback inhibition is a process in which the reaction is controlled by the end product.

Radiation effect is a process in which enzymes are inactivated rapidly by exposure to ultraviolet light and also to ß, γ, and X-rays, because it alters the shape of protein, i.e., enzymes.
