Complete step-by-step answer:

From the hint given to us, we know that prepositions can be used to agree with a mathematical function or to relate a numerical with another. We have also been told about the various prepositions that are used to form an agreement with the mathematical functions that are given. In order to find the correct set of prepositions we must analyze all the given options. We observe, that for the first blank we have to use a preposition that is suitable for the division. From the hint given to us, we know that the suitable preposition will be ‘by’. For the second line, we observe that 4 is shown to be related to 16 as a square root. From the hint given to us, we know that the suitable preposition will be - of.
We observe that option A has the correct set of prepositions that we have derived. Hence, it is the correct answer. The other options are wrong as they do not have the correct set of prepositions that we have derived.

 Note: Prepositions are used before a noun. Here, the noun is the number itself.
