To determine which geometric solid best models the head of a human being, let's evaluate each option based on the shape and characteristics of a human head.

1. Cylinder: While a cylinder has a uniform diameter and may represent the neck better than the head, it does not capture the rounded shape of a human head effectively.

2. Sphere: A sphere closely resembles the overall roundness of a human head. It simplifies the shape, capturing the general contour without the details of facial features.

3. Pyramid: A pyramid has a point at the top and straight sides, which does not represent the shape of a human head. It is angular and does not mimic the smooth curvature found in human anatomy.

4. Cone: A cone narrows to a point at one end, which can somewhat resemble the shape of the head, particularly if considering the profile view. However, it still lacks the rounded symmetry found in most human heads.

Conclusion:

The best geometric solid to model the head of a human being is the Sphere (B), as it most closely represents the rounded, smooth shape of the human head.
