Step 1: Understanding Pencil Grades.
Hard pencils (like H and 2H) produce lighter lines, while soft pencils (like B and 2B) create darker lines. To draw light lines, a harder pencil like 2H is used.
Step 2: Verifying the Options.
- Option (1): HB is medium and not ideal for light lines.
- Option (2): H is hard but produces lighter lines than HB.
- Option (3): 2H is harder and produces the lightest lines, making it the correct answer.
- Option (4): 2B is soft and creates dark lines.
Conclusion:
Therefore, the correct answer is (3) 2H.
