Frequency is the rate at which something occurs or is repeated over a particular period of time or in a given sample. It is not the rate at which something occurs "per second" unless further explained as such. If you read the question It specifically calls out a defined time of one second. Were frequency can be expressed in any amount of time. EX: the frequency of (cycles per min) equals 3600. the frequency of (cycles per second) equals 60.
My point is the denominator when defining frequency is a variable not one second. The denominator in the unit Hz is defined as one second.
Given that the question ends with the statement "the," it wouldn't make sense to say "the hertz" as it would to say "the frequency." Try not to overthink the question and go with what makes sense.
frequency (1) The number of periods, or specified fractions of periods, per unit time.
Note the words “unit of time” not “one minute”. We have known the definition of frequency and Hz for along time.
