ⓐ accept and knowledge both problems and find reasonable compromises while keeping the larger/global picture in mind.
ⓒ Ramp up Oil production as much as possible to sell as much Oil as possible, covertly use money and influence to make people dependent on Oil but in the country and to the press say that Climate Change needs to be stopped and Oil usage needs to degree and make your country less dependent on Oil usage (so that it has no problem when it runs out and so that you can sell more).
ⓒ Some where in between? But I assumed the hypothesis is about countries which produce Oil in a economical relevant amount, so I'm not sure there is a "unremarkable average".
As far as I can tell Norway tries to go with ⓐ but not perfectly 100% commitment, but then expected a perfect type ⓐ approach is IMHO unrealistic. For example as far as I can tell their Arctic(1) expeditions are more about being able to keep their Oil output around the current level if necessary then about ramping it up.
A country which could be saied to go with type ⓒ is Saudi Arabia I think, but I'm have vastly to little knowledge about it to make that judgement.
(1): One note about Arctic Oil mining. There is nothing which makes Arctic Oil mining inherently more climate damaging then non-Artic Oil mining. The reason many see it as a no-go is more related to environmental concerns (which are not the same as climate concerns!). Through there are also arguments about reducing the amount of Oil which can be blasted in our atmosphere by blacklisting Arctic Oil. Either way while there are many reasons to complain about it I also can think about reasons why it might make sense and why I maybe might have done such decision. (Mainly related to increasing geopolitical tensions, increasing influence of China, and the China US conflict.)
