Hydrocarbons sounds like what it is - molecules of hydrogen and carbon. They can form in things like hydrothermals, which are heated water vents. The hydrocarbons can be used as evidence for certain reactions.
That's just the general summary, so I'm not sure if this would be of much use. You'll have to look into it more from there.
Hydrocarbons are one of the primary things in oil (petroleum), so basically think about petroleum-forming conditions when it asks about hydrocarbons, and how those might be affected by tectonic features.
Also, about hydrothermals, I think it's talking about not just hydrothermal vents, but all circulation of water through seafloor sediments and basalts.
This is one part of the rules that changed since last year, so I don't really know what types of questions are normally asked about it.
