I settled on C as the right answer.Split #1:
care their sensitive pets vs
care for their sensitive pets
The right idiom is care for their sensitive pets. Care their sensitive pets is unidiomatic and hence incorrect. A can be eliminated based on this.
Split #2:
doing so vs
itdoing so is a pro - verb that can rightly refer to an action previously mentioned in the sentence. In the context of the sentence, doing so refers to the act of caring for and nurturing pets by their owners. The pronoun
it cannot have the aforementioned action as its antecedent. Hence B and D can be eliminated.
Split #3: meaning.
will result vs
may resultBetween C and E, E changes the meaning of the sentence. The original sentence expresses a sense of higher possibility with the use of
will result. In E, however,
will result is replaced with
may result, and by so doing implying a lesser likelihood of the act of nurturing and caring for pets by their owners to result in a calm temperament and healthy physique. E thus changes the meaning of the original sentence. Hence E is inferior to C, which maintains the original meaning of the sentence.
