The author's conclusion is that it's unlikely Juan was at a party. Why? Because if Juan had been at the party, it would be unlikely Maria would have enjoyed the party—but Maria did enjoy the party.
To find the method of reasoning, we first need to describe the abstract pattern underlying the argument. Having done so, we'll then be able to find a matching argument in the answer choices. Boiling down the argument to an abstract structure, it looks like this:
Juan attended → unlikelyMaria enjoyed
Maria enjoyed
______
unlikelyJuan attended
So we're looking for three elements for the correct answer: a premise claiming that if one event occurs, another is unlikely; a premise affirming that the latter event occurred; and a conclusion that the first event is unlikely.
Keep in mind, the order of these elements is less important: the right elements out of order still make up the same logical structure. It will probably be straightforward to eliminate several answer choices that clearly don't match this structure, but we might end up with two possible answers that are hard to choose between. At that point, it's important to examine each option closely so we can choose one based on the exact details of the argument.
