The statement about the situation that is implicit in these lines is that Ginger received sad news. Option C is corret.
Since she has a letter in hand, and it is described that she started to cry, we may infer that the reason why she is crying is because she read something really sad in that letter.
The meaning of implicit is, “implied or understood though not plainly or directly expressed.” Hence, something is implicit when it is not directly stated but is either suggested in the wording. In this case, the description if the actions reveals the implicit situation.
