The reason for the superior performance of James is <u>his brain has experienced greater myelination than Mark's.</u>

Explanation
Mass is a quantity commonly used in areas such as physics and chemistry that expresses the amount of matter that an object has. The unit of measurement for mass is the kilogram (kg), as well as its derived units such as the gram, milligram, among others. However, it should not be confused even with weight (which is used to express the intensity with which a body is attracted by a gravitational field). On the other hand, a bicycle is an artifact or means of transport that uses a system of gears to move. Bicycles generally have a mass of 10kg, so the correct answer is C. About 10 kilograms.
