how do fossils of the animal Archaeopteryx provide evidence that birds evolved from one group of dinosaurs?

Question

a. Fossils of Archaeopteryx are older than fossils of birds, but younger than fossils of dinosaurs.
b. Fossils of Archaeopteryx were discovered near fossils of both dinosaurs and birds.
c. Fossils of Archaeopteryx have traits that show they were better able to survive than dinosaurs, but less able to survive than birds.
d. Fossils of Archaeopteryx have traits of both dinosaurs and birds.

Answer 1

d. Fossils of Archaeopteryx have traits of both dinosaurs and birds. This suggests that Archaeopteryx represents an intermediate stage in the evolution of birds from dinosaurs, providing evidence for the evolutionary link between these two groups.
