Solution
The correct option is D
Mandibles, Proventricular teeth, Symbiotic bacteria and Protozoa.
Cockroaches do have an amazing ability to eat the inedible. The anatomical adaptations seen in the roach are mandibles and proventricular teeth while the physiological adaptations are the association with symbiotic bacteria and protozoa which help it in digesting non-biological matter.
