Answer: (A)

Verified step by step guidance

1. Begin by identifying the location and function of the cranial cavity. The cranial cavity is the space within the skull that houses the brain.
2. Understand the anatomy of the skull. The skull is composed of several bones that protect the brain and form the structure of the head.
3. Identify the bones that contribute to the lateral walls of the cranial cavity. The lateral walls are primarily formed by the temporal bones and parietal bones.
4. Determine the bones that contribute to the floor of the cranial cavity. The floor is formed by the occipital bone and parts of the temporal bones.
5. Recognize the frontal bone's role. While the frontal bone forms the forehead and part of the roof of the cranial cavity, it does not contribute to the lateral walls or floor.
