If the traits for white fur and red eyes were always inherited together then the hypothesis would not have been supported by the data.
Explanation:
The white fur and red eyed mouse had genotype AA RR or AaRr
The black fur mouse and black eye mouse had genotype aarr
The F1 offspring will have all offspring with same phenotype as shown in the Punett square.

Punnet square to show that genes assort independently.

The phenotype pattern of this punnet square shows that white fur and red eyes are not always inherited.
The law of independent assortment is shown from the cross that is by selfing.

By cross checking, the options given it is concluded that the traits for white fur and red eyes are not always inherited together, the two traits are governed by different genes and are independently exhibited in the individual as stated in law of independent Assortment.
