The Correct Option is B

Solution and Explanation

In engineering drawings, different line types convey different meanings.
Lines made up of short, evenly spaced dashes are used to indicate hidden edges.
These are the edges that are not visible from a specific viewpoint because they are behind or inside an object.
Such lines help in visualizing features that are otherwise obscured in the view, enhancing the understanding of complex parts.
By contrast, visible edges use continuous thick lines, and hatching uses thin diagonal lines for section views.
Thus, the correct representation for these dashed lines is (B) Hidden edges.
