OPTIONS
(A) Bacteria
(B) Parasite
(C) Both (a) and (b)
(D) Endogenous enzymes
ANSWER
(D) Endogenous enzymes

Food irradiation can effectively reduce bacteria and parasites at appropriate doses, but endogenous food enzymes are comparatively resistant and may remain active unless separately inactivated, for example by heat. Therefore, bacteria and parasites are not the best answer, whereas endogenous enzymes are. Option (D) is correct.
