Question

10 multiple choice 1 point when is a dimension line used? to indicate an objects center to indicate and objects edge to show a measurement to show an object

Explanation:

A dimension line in technical drawing (related to engineering or design) is specifically used to show the measurement of a feature, like length, width, or height of an object. The first option is for center lines, the second (with a typo "and") is incorrect as edge indication is not the role of dimension lines, and the last option is wrong as dimension lines don't show the object itself. So the correct reason is that dimension lines show measurements.

Answer:

C. to show a measurement (assuming the options are labeled A, B, C, D with the third option as C)
