Final answer:
The mandible is the bone that features a ramus and an angle. It is the lower jawbone and is the only movable part of the skull.
Step-by-step explanation:
The bone that has a ramus and an angle is the mandible (A). The mandible is the lower jawbone in humans and is the only movable bone of the skull. It has two main parts: a horizontal body and two perpendicular rami that join the body at the angles of the mandible.
Each ramus has a flat, vertical projection that can easily be felt just in front of the ear. The point where the body and ramus meet, which is palpable from the exterior, is known as the angle.
