I got this question during a job interview.

My question is from Terminology of Dimensioning in chapter Lines, Lettering and Dimensioning of Engineering Drawing

Answer 1

Correct choice is (c) The leader is drawn vertical or horizontal or curved.

Easy explanation: The leader is never drawn vertical or horizontal or curved. It is drawn at a convenient angle of not less than 30o to the line to which it touches. When pointing to a circle or an arc it is drawn radially.
