The answer is C because A cannot be true, since it is in a very hot and dry climate, then we move onto B, which can also not be true, since poor environmental factors do not make a thick ringed tree, since it needs good conditions to grow, and rings measure how much it grows, so a thick ring means it grew a lot in that year, then we move onto C, which would match up, because the rings are thick, and then D, which cannot be true since a tree would not thrive in an icy environment, since it is not ideal for nutrients and sunlight.
