Answer:
Orbicularis oris
Explanation:
Orbicularis oris muscle is present in the lips. These muscles may lie horizontally or vertically with other muscles.
Orbicularis oris is the circular muscle that encircles the mouth. This muscle is also known as kissing muscle. Orbicularis oris muscle originates from the maxillae and mandible and innervated by the facial nerve. This muscle inserts in the lips margin.
Thus, the correct answer is option (B).
Item A is different from item B by the crust in item A which is found partially below sea level as compared to the crust in item B. Thus, the correct option is C.
<h3>What is Crust?</h3>
The crust may be characterized as the outermost shell of a terrestrial planet. It is a narrow covering on the outside of Earth.
The surface of item A tends to have an irregular surface across the plain, while the surface of item B tends to have a flat and definite surface throughout the plain.
It estimates the position of the crust of a particular surface with respect to its structural appearances.

<h3>What is
gnathostomes?</h3>
The jawed vertebrates are called gnathostomata. The phrase comes from the Greek words "jaw" and "mouth." Approximately 60,000 species make up the diversity of the gnathostome, which represents 99% of all vertebrates still alive today.
<h3>What is
osteichthyans?</h3>
A broad taxonomic group of fish called osteichthyes, also known as the "bony fish," has skeletons that are predominantly made of bone tissue.
<h3>What is
lobe-fins?</h3>
The taxon Sarcopterygii, also known as Crossopterygii, is made up of bony fishes noted for having lobe-finned fishes as its members.
<h3>What is
