4. Does not pass through the center of the sphere

Answer 1

1. Is the correct definition of the diameter of a sphere. It represents the distance from the center of the sphere to any point on its surface.
2. Is also correct, as the diameter is indeed the longest distance that can be measured on a sphere.
3. Is incorrect. The diameter is equal to twice the length of the radius, not half.
4. Is incorrect. The diameter always passes through the center of the sphere.
