He is wealthy enough to live in West Egg but not wealthy enough to rent a very nice place.
Nick describes his place as "an eyesore". This detail shows us that the place he's renting is not nice in comparison to the other homes in West Egg. We also know that he must have some wealth in order to afford to pay eighty dollars a month during this time period. From this excerpt, there is no indication that Nick's choice to live in the small house is temporary or that he seems desperate to become part of the elite society. He may be impressed by material wealth because he describes the proximity of the millionaires as "consoling", so option A is also not a good choice.
