Step 1: Understanding Pencil Hardness and Darkness.
The "B" scale represents soft pencils, which produce darker lines. The higher the "B" number, the softer the pencil and the darker the line. The "H" scale represents harder pencils, which produce lighter lines.
Step 2: Verifying the Options.
- Option (1): 2H is a hard pencil and produces lighter lines.
- Option (2): 2B is a softer pencil and produces darker lines, making it the correct answer.
- Option (3): 4H is an even harder pencil, producing lighter lines.
- Option (4): H is also a hard pencil, producing lighter lines.
Conclusion:
Therefore, the correct answer is (2) 2B.
