my guess would be c because:
a is wrong because i don’t think there would be many glaciers where elk and sharks are
b is wrong because although there was an ocean that sharks could live in, there are still elk and they don’t live in the water
and d is wrong bc i don’t think elk or any other animal would like it to be super cold, also a means it would be cold and a is wrong.
(also i am not 100% sure this is just a guess) - hope this helps
