Based on the description you provided, the correct statement is:

The roller coaster’s kinetic and potential energy change from location to the next, but its total energy remains the same.

In a roller coaster, energy is conserved, meaning that the total mechanical energy (potential + kinetic) remains constant, while energy transforms from one type to another as the coaster moves through different heights and speeds.
