B. It increases.

Explanation:

The kinetic energy is associated with the motion of the particles of a substance.

When the temperature increases, the movement will increase, which means that the velocity of the particles will increase.

According to the mathematical defenition of kinetic energy

$Ek = \frac{1}{2} mv^{2}$

The higher the velocity, the higher the kinetic energy.

If the matter is made by a monoatomic gas, the relation between the kinetic energy and temperature is even more evident:

$Ec = \frac{3}{2}\frac{R}{Na} T$

R: gas constant

Na: Avogadro's number

T: temperature
