The correct choice pertains to the classification of affinity, which refers to the relationship established through marriage rather than blood. In this context, second-degree relatives of affinity typically include a spouse's grandparents.

When considering relationships by degree of affinity:

- A spouse's grandparents are two generations away from the spouse, which categorizes them distinctly as second-degree relatives.

- The other relationships mentioned either fall into the first degree of affinity or farther removed. For instance, children's spouses are considered first-degree relationships, as they are the in-laws of the person. Likewise, spouse's great-grandparents are at a higher generational level, making them a third-degree relationship. Spouse's uncles and aunts, while also relatives, remain at the first degree of affinity.

Thus, the selection highlights a proper understanding of family relationships as classified by marriage, identifying the correct nature of second-degree affinities.
