Answer 1

The correct answer is Long dashed double dotted narrow line.

Key Points

If the unit has one or more moving parts, the extreme positions of the moving parts are indicated in the Long dashed double-dotted narrow line.
The long, thin, dashed-dotted line is used to show an object's axis as well as the centers of circles and arcs.
The long dashes are roughly 10 mm long, and there is a 1 mm gap between each long dash and dot.
Dimension lines, construction lines, and leader lines are all made up of continuous narrow lines.

Important Points

The continuous thick line is utilized to demonstrate the edges or apparent outlines of a component or assembly. If there are too many lines close together and the drawing is crowded, this line might be made thinner to improve the drawing's clarity.
The most common line type on engineering drawings is the continuous thin line. There is no break in these lines, which are solid.
