B.

The fossils show gradual changes in anatomy (feet, teeth, body size/shape) over time, supporting descent with modification — modern horses evolved from earlier horse species. Options A, C and D are contradicted by the evidence: changes are not limited to feet/teeth, species did not spontaneously generate, and modern organisms are not identical to their ancestors.
