The correct statement is: It increases the kinetic energy.
Kinetic energy (KE) is given by the formula:
\[ KE = \frac{1}{2} mv^2 \]
where \(m\) is the mass of the object and \(v\) is its velocity. From this formula, you can see that if the mass \(m\) of the object increases and the velocity \(v\) remains constant, the kinetic energy will also increase.
