Mark the rule which is not correctly stated about the determination of...
**Explanation:**
The rule stated in option B is not correct. Zeros between two non-zero digits are actually significant.
**Significant Figures:**
Significant figures are the digits in a number that carry meaning in terms of precision or accuracy. They indicate the level of certainty or uncertainty in a measurement or calculation.
**Correct Rules for Determining Significant Figures:**
1. **Non-zero digits:** All non-zero digits are significant. For example, in the number 1234, all four digits are significant.
2. **Zeros preceding the first non-zero digit:** Zeros that come before the first non-zero digit are not significant. For example, in the number 0.0056, the zeros before the 5 are not significant.
3. **Zeros between two non-zero digits:** Zeros that appear between two non-zero digits are significant. For example, in the number 1005, the zero between the 1 and 5 is significant.
4. **Zeros at the end or right of the number:** Zeros at the end or right of the number are significant if they are on the right side of the decimal point. For example, in the number 0.0500, all three zeros at the end are significant.
**Explanation of Incorrect Rule (Option B):**
The rule stated in option B is incorrect. Zeros between two non-zero digits are significant. This means that in numbers such as 1005, 2006, or 5004, the zeros between the non-zero digits are significant and should be counted as significant figures.
For example, in the number 1005, there are four significant figures: 1, 0, 0, and 5. The zero between the 1 and 5 is significant and should not be ignored.
Therefore, the correct rule is that zeros between two non-zero digits are significant.
