Meaning error

This question test the concepts of 'agreement' and 'logical prediction' . Dinosaur is singular noun and cannot be presented by plural nouns (them, their) and non-underlined portion "not extended..." confirms that subject of main clause should be dinosaurs"

Option A & B : we can straight away eliminate as them / they / their are plural pronoun and require plural subject, but dinosaur is singular. So no antecedent

Option C : Here the subject of main clause is "track", which will not agree with non-underlined portion

Option D : Correct choice as plural noun dinosaurs is used, and subject of main clause is dinosaurs

Option E : Passive voice somehow changes the meaning of the sentence
