A

Dark fur would be most common, but there could be a few mutations.

B

Golden would be most common, but there could be a few mutations.

C

Dark fur would be growing more common, and light fur would be growing less common.

Yes - there's only one kind of mutation that can result in dark fur.

No - different mutations appeared randomly, and the ones that resulted in dark fur became more common. 

Individual mice changed their traits in order to survive. 

Mice with light fur color moved to golden desert and mice with dark fur color moved to black lava rock.

Mice with that fur that matched their environment were more likely to survive, reproduce, and pass on their genes to the next generation. 

In order to survive, the mice passed on genes that allowed their offspring to blend into their environment.

The original black mouse survived longer and reproduced more, causing the trait to become more common over time. 

Parent mice gave helpful genes to their offspring. 

Brown and golden mice that lived on the black lava changed their genes to survive. 

Black mice moved to the black lava where they could blend in.
