Step-by-step explanation:

A set of ordered pairs are one-to-one function if and only if one x-coordinate is only paired to one y-coordinate and vice versa.

For Option A, no x-values and no y-values are repeated hence, Option A is one-to-one.

For Option B, we see that the y-coordinate 5 is paired to two x-coordinates that are -9 and 10.

Hence, Option B is not one-to-one.

For Option C, no x-values and no y-values are repeated hence, Option C is also one-to-one.

To summarize, Options A and C are one-to-one. Option B is not one-to-one.
