Respuesta :
The correct answer is D - this is a compound sentence, which means it consists of at least two independent clauses, in this case they are:
1. The saber-toothed cat was a fierce and hardy hunter
2. It once roamed throughout North and South America.
Independent clauses can exist. on their own, they are completed, as opposed to subordinate clauses.
