Right Answer is: C
SOLUTION
Explanation:
Pencils are graded according to the hardness or softness of the lead.
The hardest pencil is 9H grade and softest pencil is 7B grade.
Selection of grade of pencils depends on the type of line work required and paper on which it is used.
- Softer lead pencils are used to produce thicker and darker line work, but they wear out quickly
- Medium grade of H, 2H is used for general line work as well as for lettering
- Harder grade leads to produce lighter and thinner lines
Most construction line work is done with 4H, 5H and 6H pencil leads, producing thin but also sufficiently dark by exerting pressure.
For any drawing on drawing paper or tracing paper, H, 2H or 3H pencils are selected.
