They are more closely related to salamanders than they are to birds.

Explanation:

According to the data, trout are more closely related to salamanders than birds.

The first data table shows how the salamander only has one extra trait that the trout does not have (lungs).

On the other hand, birds have three extra traits that the trout doesn't have (claws/nails, feathers, and lungs).

The cladogram further shows how trout are more closely related to salamanders compared to birds.

Trout and the salamander are closer together on the cladogram, while the bird is further away. This means they are more related on the evolutionary timeline.

So, the correct answer is that They are more closely related to salamanders than they are to birds.
