C doesn't seem right. It will be interpreted as, "There exists a corgi, such that every person loves that corgi".
But our implication in question goes on way only. Person loves at least corgi. There maybe corgis that no one loves. So, C seems wrong.
B seems correct, it can be interpreted as "For each person, there exists a corgi that is loved by that person."
A is correct.
What do you say?
