Step 1: Understanding Pencil Hardness.
Pencils are graded based on their hardness and softness. The "H" scale refers to harder pencils that leave lighter lines. The higher the "H" number, the harder the pencil and the lighter the line. Conversely, the "B" scale refers to softer pencils that leave darker lines.
Step 2: Verifying the Options.
- Option (1): A 1 H pencil is hard, and it produces a light line due to its hardness.
- Option (2): 2 H is harder than 1 H, but it still produces a relatively light line, though slightly darker than 1 H.
- Option (3): HB is a balanced pencil, and it produces a medium-dark line.
- Option (4): 2 B is a soft pencil and produces a dark line.
Conclusion:
Therefore, the correct answer is (1) 1 H.
