Choice A rationale
Raw carrots do not contain vitamin B12. Vitamin B12 is not naturally found in plant foods.
Choice B rationale
Fresh citrus fruits do not contain vitamin B12. Vitamin B12 is not naturally found in plant foods.
Choice C rationale

Choice A rationale
Maternal cytomegalovirus (CMV) infection is a serious health concern as it is associated with severe birth defects like sensori-neural hearing loss, impairment of cognitive development, and cerebral palsy. It is acquired by contact with body fluids and by vertical transmission from mother to fetus. Transmission can occur via the saliva and urine of the newborn, which is why this is the correct answer.
Choice B rationale
CMV does not require airborne precautions. It is not an airborne disease; it is spread through close, direct contact with a person infected with the virus.
Choice C rationale
CMV does not cause visible lesions on the mother’s genitalia. This is a characteristic of other sexually transmitted infections, not CMV2.
Choice D rationale
Mothers do not receive prophylactic treatment with acyclovir prior to delivery to prevent CMV2. Acyclovir is an antiviral medication used to treat herpes simplex virus infections, not CMV2.
