It's easy to eliminate A, B, D and E as possible answers, but the statement that Laura and Marco want lightweight jackets doesn't eliminate the possibility that those jackets may have hoods. The statement that "nobody wants a lightweight jacket with a hood" is also ambiguous. Does that mean that they wouldn't be happy with such a jacket or simply they they don't require it? If I say that "I don't want to go to the park," most native-English speakers would interpret that as me being unhappy if we were to go the park. Laura and Marco don't explicitly need a hood, although that assumes that the description of what they want is complete and exclusive of anything else, but they wouldn't necessarily mind having one.
In any case, I like questions like this primarily for the opportunity to analyze the question itself.
This was my line of thinking as well. When I saw that someone answer none of the above, I was like damn, didn't think that was an option. This isn't a think outside of the box thing is it?
Like you said, C is the only answer that can't be eliminated but also doesn't mean it is the correct answer imo because of the reasons you stated.
