Verified step by step guidance

1. Identify the conversion factor between meters and centimeters. Since 1 meter equals 100 centimeters, we use the factor 100 cm / 1 m.
2. Set up the conversion by multiplying the given length in meters by the conversion factor: \$0.129 \text{ m} \times \frac{100 \text{ cm}}{1 \text{ m}}$.
3. Notice that the unit meters (m) cancels out, leaving the result in centimeters (cm).
4. Perform the multiplication of the numerical values: \$0.129 \times 100$ (do not calculate the final value here, just set up the expression).
5. The result from the multiplication gives the length in centimeters, which corresponds to the correct answer choice.
