Soft pencil leads are indicated by which letter?

1. B

2. F

3. H1

4. H

The correct answer is: B

Soft pencil leads are denoted by the letter B. The B scale is specifically designed to indicate softer leads, which produce darker marks on paper compared to harder leads. As the number preceding the B increases, the lead becomes softer, allowing for a greater range of darkness when writing or drawing. In contrast, leads marked with H are harder and create lighter lines, while F leads represent a pencil that is more flexible, falling between B and H in terms of softness and hardness. Therefore, understanding the grading system helps in selecting the appropriate pencil based on the desired darkness of lines and the specific needs of a drawing or writing project.
