Question

introduction to print reading: identify the line indicated by b * 1 point

Explanation:

Object lines are used to represent the visible edges of an object in technical drawings. In the given diagram, the line indicated by B is a solid line that outlines the visible part of the object. Center lines are typically used for symmetry or to indicate the center of circles/arcs (not the case here). Hidden lines are dashed (not the case here). Dimension lines have arrows at the ends and are for indicating measurements (C is a dimension line). Extension lines are for extending from the object to the dimension line (A is an extension line). Since B is a solid line representing a visible edge, it is an object line.

Answer:

Object Line
