Answer: D

Explanation: The following concepts are used here:

1. Comparison
2. Sentence construction

Option A: Incorrect
This option is incorrect because the use of “dinosaur tracks” seems awkward and illogical. It seems to be the name of a track rather than the showing possession. Also, the “their” used in this option does not modify the single dinosaur and instead points to the tracks. Other more appropriate phrases could be used in place of it. So, Option A is incorrect.

Option B: Incorrect
This option is incorrect because the pronoun used in this option “they” is referring to the “dinosaur tracks”, which does not make any sense. Tracks cannot walk and some other more appropriate phrase could be used in place of dinosaur tracks. So, Option B is incorrect.

Option C: Incorrect
This option is incorrect because the construction of this choice is not proper. The “like” used here is not correct as we are comparing two actions, one by the dinosaurs and the other by the mammals and birds, so we can not use like in this situation. Since the option uses incorrect and awkward phrases, Option C is incorrect.

Option D: Correct
This option is correct because this option has clearly mentioned the dinosaurs earlier in the sentence and it uses the pronoun “they” that can be clearly attributed to the dinosaurs and not to the tracks. The construction of this choice is proper and lacks awkwardness and redundancy. So, Option D is correct.

Option E: Incorrect
This option is incorrect because this sentence is poorly constructed. The phrase “in the tracks they left” seems awkward and illogical. There are many other appropriate options that could have been used in place of “in the tracks, they left”. So, Option E is incorrect.
