Answer:
The best option for this problem would be the second option: "The percentage of the population with white fur will decrease"
Step-by-step explanation:
Think about animals up in the north. Most of them are white because it helps them blend in the snow. And so an increase in average temperatures would mean less snow time. This would mean that the white rabbits will be more vulnerable to attacks for a longer time period of the year compared to previous years with a short time period of being vulnerable.
