The unit used to describe frequency in the material is

Frequency means how many cycles happen each second, so the unit must describe cycles per unit time. Cycles per second does exactly that, naming the rate at which repeating events occur every second. In SI terms, this is the same quantity as hertz, with 1 hertz equaling 1 cycle per second, so cycles per second and hertz describe the same frequency. The other options measure different things: meters per second is speed, and newtons are force. So cycles per second is the direct way to express frequency as the rate of cycles per second.
