In P 0.00 is non significant so it has 2 significant figures,
Q has 3 since after decimal digits are counted and S has 4 since all the 4 digits are significant. option A is correct

Significant Figures
Significant figures are the digits in a number that are meaningful and contribute to its precision. When performing calculations with measurements or data, it is important to consider the number of significant figures in each value to ensure accurate results.
Identifying the Number of Significant Figures
To identify the number of significant figures in a value, follow these rules:
1. Non-zero digits are always significant.
2. Leading zeros (zeros to the left of the first non-zero digit) are not significant.
3. Captive zeros (zeros between non-zero digits) are always significant.
4. Trailing zeros (zeros to the right of the last non-zero digit) are significant if there is a decimal point in the number.
5. Exact numbers (such as integers or defined constants) have an infinite number of significant figures.
Answering the Question
Using the rules above, we can determine the number of significant figures in each value given:
- P=0.0030 m: The non-zero digits (3) and the captive zero are significant, while the leading zero is not. Therefore, there are two significant figures.
- Q=2.40 m: All digits are non-zero, so they are all significant. Therefore, there are three significant figures.
- R=3,000 m: The trailing zeros are only significant if there is a decimal point, which is not present in this case. Therefore, only the non-zero digits (3) are significant. Therefore, there is only one significant figure.
Therefore, the correct answer is option A: 2 significant figures in P, 3 significant figures in Q, and 4 significant figures in R.

Therefore, the correct answer is option A: 2 significant figures in P, 3 significant figures in Q, and 4 significant figures in R.
