and must serve to connect PARALLEL FORMS.
B: in humans and other mammals, and in birds
C and E: in humans, other mammals, and in birds
In each of these options:
The two red phrases = PREPOSITION + NOUN.
The blue phrase = NO PREPOSITION + NOUN.
The result is a lack of parallelism.
Eliminate B, C and E.

The intended meaning is that only certain microorganisms -- ARTERIVIRUSES -- cause digestive and respiratory infections.
Eliminate D.

The correct answer is A.
