The correct answer is

Hertz

Frequency measures the number of cycles or oscillations per second. Its SI unit is the hertz (Hz), where \(1\,\text{Hz}=1\,\text{cycle/second}\), named after Heinrich Rudolf Hertz.

Newton is the unit of force, watt of power, and farad of capacitance — none measures frequency.
