(b) Top view

(c) Side view

(d) Isometric view

This question was addressed to me by my school teacher while I was bunking the class.

I would like to ask this question from Projection of Line Contained by Plane in section Projection of Lines of Engineering Drawing

Answer 1

The correct answer is (b) Top view

To explain: Any line that lie or parallel to any of plane in projection planes the true length will be found at view which drawn on to that plane that is here the line is in horizontal plane though it is inclined with other planes the true length will be given at view which fall on horizontal plane which is top view.
