Answer
A

Explanation

For fur, the cross Bb × bb can produce Bb offspring with black fur or bb offspring with white fur. For eye color, every offspring gets E from the first parent and e from the second, making all offspring Ee with black eyes. Therefore, the possible phenotypes are black fur with black eyes and white fur with black eyes.
