Which term means the distance across the center of an object?

Diameter is the straight-line distance across an object that passes through its center. For a circle or sphere, it connects two points on the boundary and goes right through the middle, so its length is twice the radius. Distal describes being farther from a reference point, discrete means separate or distinct, and dilate means to enlarge. None of those capture the notion of a line that crosses the center of the shape, so diameter is the correct term.
