Since the actual value of the atomic radius of platinum  atoms was not given in the problem, I chose 175 pm which gives an error of 18.28%.

The actual atomic radius of platinum atoms is 175 pm

We can see from the question that the measured value of the  atomic radius of platinum  atoms was determined to be 143 pm.

Recall that;

Percent error = Absolute value of (measured value - actual value)/actual value * 100

Since the actual value of the atomic radius was not given, let us take it to be 175 pm for the purpose of this problem

Percent error = Absolute value of (143 - 175)/175 * 100

Percent error = 18.28%

The percent error of this measured value ; ( D ) approximately 13%

The percent error of a measured value

= [ ( actual value - measured value ) / ( actual value ) ]  * 100

= [ ( 175 pm - 143 pm ) / ( 175 pm ) ]  * 100

=  18.29%

From the options given the closest value to the calculated value is 13%

Hence we can conclude that the percent error of this measured value is approximately 13%.
