Answer :
Final answer:
The higher the precision, the smaller the unit of measurement. Therefore, the most precise option in this set is 5.00 mm.
Explanation:
The most precise measurement in this list is Option 1: 5.00 mm. Here's why: precision refers to the smallest unit of measurement that gives detailed information. Although all the measurements represent 5 units, the unit in mm (millimeters) is much smaller than cm (centimeters), m (meters), and km (kilometers). Therefore, using mm gives a more detailed, hence, more precise measurement.
Think about it this way, if we were to break a meter stick or rule, a millimeter would give us more specific information than a centimeter, meter, or kilometer. It's the equivalent of measuring with a finely-graduated ruler as against a coarse one. With more graduations, or divisions, we’re capable of specifying length more exactly and thus, more precisely.
Conclusion
The smallest division/unit provides the highest precision. Consequently, in this context, 5.00 mm is the most precise measurement.
