Step 1: Understanding Brush Sizes.
Brushes come in a range of sizes, with smaller numbers typically representing finer, more detailed brushes. The number 0 is typically used for fine lines, as it refers to the smallest available size in many brush types, making it ideal for detailed work. Larger numbers, like 2 and 4, are used for broader strokes and less detailed work.
Step 2: Verifying the Options.
- Option (1): A size 6 brush is relatively large and not suitable for fine lines.
- Option (2): A size 4 brush is larger and better for medium strokes.
- Option (3): A size 0 brush is the finest brush, best for fine lines and intricate details.
- Option (4): A size 2 brush is larger than 0 and not ideal for fine lines.
Conclusion:
Therefore, the correct answer is (3) 0.
