Geometry

The answer is B.A line has length but no width.

Analyze each option:

A.A line has no length and no width: This description fits a point, not a line. A point is a dimensionless object that represents a location in space and has no length, width, or thickness. So this option is incorrect.

B.A line has length but no width: In geometry, a line is defined as a one-dimensional object that extends infinitely in both directions. It has length but no width or thickness. This option correctly describes a line.
