The correct answer is Option 2.

Explanation:

To calculate the percentage error, we use the equation:

$\%\text{ error}=\frac{|\text{Experimental value - Actual value}|}{\text{Actual value}}\times 100$

We are given:

Experimental value of circumference = 60.0 cm

Actual value of circumference = 63 cm

Putting values in above equation, we get:

$\%\text{ error}=\frac{|60.0-63|}{63}\times 100\\\\\%\text{ error}=4.8\%$

Hence, the correct answer is Option 2.
