The chief advantage of the metric system over other systems of measurement is that it a. has more units b. is in multiples of 10 c. is in multiples of 15 d. is derived from nature itself

The chief advantage of the metric system over other systems of measurement is that it B. is in multiples of 10.

This can be seen in the picture below that shows the prefixes of the metric system.

The correct answer is option B, that is, is in multiples of 10.

Explanation:

The metric system refers to an internationally acclaimed decimalized system of measurement. It is used globally, and it is the most usual or the only system of measures and weight in the places where it is adopted.  

As the metric system is a decimal system of measures and weight, it is easy to transform in between the units, for example, from grams to kilograms, or from millimeters to meters, basically by dividing or multiplying by 10, 100, 1000, and others. Usually, this is the case of moving the decimal point to the left from the right.
