From the given options, primitive fishes first appeared on earth about 530 million years back, during the time of Cambrian. Next to this, the giant insects appeared some 410 million years back during the early Devonian period. After this, the reptiles appeared about 310 million years back during the late Carbonaceous period. And lastly, the horses appeared about 55 million years back during the time of Eocene period.

Thus, the position of primitive reptiles and giant insects must be interchanged.

Hence, the correct answer is option (B).
