Correct option is A
Mini Drafter:
A mini drafter is a technical drawing instrument commonly used for precise engineering drawings.
It combines the functions of a T-square and set squares and allows users to draw parallel lines, perpendicular lines, and various angles without switching tools.
Let us understand the role of these instruments:
T-square and Set squares:
The T-square is used to draw horizontal lines on a drawing sheet, while set squares are used to draw angles like 30°, 45°, 60°, and 90°.
A mini drafter provides both functionalities in a single tool, making it easier and faster for technical drawing.
