Answer: (A)

Verified step by step guidance

1. Understand the context: A typical shampoo bottle is a common household item, so its volume is usually measured in milliliters (mL) or liters (L). Consider what volume would be practical for daily use.
2. Compare the given options: 0.3 mL, 30 mL, 300 mL, and 3 L. Think about how much shampoo you would expect to use in one bottle and how these volumes relate to everyday experience.
3. Recall that 1 liter (L) equals 1000 milliliters (mL), so 3 L is 3000 mL, which is quite large for a shampoo bottle and more typical for bulk containers.
4. Recognize that 0.3 mL is extremely small—less than a drop of liquid—so it is not a reasonable volume for a shampoo bottle.
5. Conclude that 300 mL is a reasonable estimate because it is a moderate volume commonly found in personal care products like shampoo bottles.
