Answer 1

The upper fourth premolars of a dog are known as carnassials, which are specialized teeth used for shearing flesh and cracking bones. So, the correct answer is option d.

Step-by-step explanation:

The upper fourth premolars of a dog are known as carnassials. Carnassials are specialized teeth found in some carnivorous mammals that are used for shearing flesh and cracking bones. They have a blade-like shape and a modified cutting edge that allows efficient tearing and cutting of meat. In dogs, the carnassials are located in the upper jaw and consist of the fourth upper premolar and the first lower molar.

So, the correct answer is option d.
