[Solved] The hidden parts inside or back side of object while represented in orthographic projection are represented by which line?

Q.	The hidden parts inside or back side of object while represented in orthographic projection are represented by which line?
A.	continuous thick line
B.	continuous thin line
C.	dashed thin line
D.	long-break line
Answer» C. dashed thin line
Explanation: continuous thick line is used for visible outlines, visible edges, crests of screw threads, limits of full depth thread etc. continuous thin line is used for extension, projection, short centre, leader, reference lines, imaginary lines of intersection etc.
