I could be wrong but I think this would the answer for this.

The answer is 4) A unit rate always relates quantities with the same units.

Step-by-step explanation:

It cannot be 1 because a unit rate relates a quantity to 1. Hence the word unit which means single or undivided whole.

It cannot be 2 because you can indeed use unit rates to compare two rates. In fact we do all the time in math! Just like comparing fractions.

It cannot be 3 because the rate has to be equivalent to its unit rate or else its wrong.

Thus making it four!
