b) False

The statement is not always true. The work done by the resultant force is equal to the change in kinetic energy only in the absence of other non-conservative forces, such as friction or air resistance. In the presence of such forces, the work-energy theorem may not hold, and the work done by the resultant force may not equal the change in kinetic energy.
