To determine the number of significant figures in a given number, we need to follow a set of rules:
1. Non-zero digits are always significant.
2. Zeros between non-zero digits are always significant.
3. Leading zeros (zeros before the first non-zero digit) are not significant.
4. Trailing zeros (zeros after the last non-zero digit) are significant if there is a decimal point present.
5. Zeros that act as placeholders (e.g., in 100 or 1000) are not significant unless specified by a decimal point.
Now let's apply these rules to the given numbers:
1. 161 cm:
- The number has three non-zero digits, so all three digits are significant.
- Therefore, there are 3 significant figures.
2. 0.161 cm:
- The number has three non-zero digits, so all three digits are significant.
- The leading zero is not significant.
- Therefore, there are 3 significant figures.
3. 0.0161 cm:
- The number has four non-zero digits, so all four digits are significant.
- The leading zero is not significant.
- Therefore, there are 4 significant figures.
Hence, the correct option is 'c' where the number of significant figures for the three numbers is 3, 3, and 3, respectively.
1. Non-zero digits are always significant.
2. Zeros between non-zero digits are always significant.
3. Leading zeros (zeros before the first non-zero digit) are not significant.

5. Zeros that act as placeholders (e.g., in 100 or 1000) are not significant unless specified by a decimal point.
Now let's apply these rules to the given numbers:
1. 161 cm:
- The number has three non-zero digits, so all three digits are significant.
- Therefore, there are 3 significant figures.
2. 0.161 cm:
- The number has three non-zero digits, so all three digits are significant.
- The leading zero is not significant.
- Therefore, there are 3 significant figures.
3. 0.0161 cm:
- The number has four non-zero digits, so all four digits are significant.
- The leading zero is not significant.
- Therefore, there are 4 significant figures.
Hence, the correct option is 'c' where the number of significant figures for the three numbers is 3, 3, and 3, respectively.
