Step 1: Understanding Pencil Hardness.
The "B" scale refers to softer pencils that produce darker lines. The higher the number, the softer the pencil, and the darker the line.
Step 2: Verifying the Options.
- Option (1): 2B is a softer pencil, but 4B is even softer and produces darker lines.
- Option (2): 4B is the correct choice for drawing dark lines as it is a soft pencil.
- Option (3): 2H is a hard pencil and produces light lines.
- Option (4): HB is a medium pencil and produces medium
-dark lines.
Conclusion:
Therefore, the correct answer is (2) 4B.
