Which of the following would be considered a GFS backup solution?
The correct answer is C. Yearly, monthly, daily. The Grandfather-Father-Son (GFS) backup solution is a hierarchical rotation scheme that defines how frequently backups are taken and how long they are retained, commonly structured around yearly, monthly, and daily backups.

Why each option
The Grandfather-Father-Son (GFS) backup solution is a hierarchical rotation scheme that defines how frequently backups are taken and how long they are retained, commonly structured around yearly, monthly, and daily backups.
Grouped, full, supplemental is not a standard GFS terminology or backup rotation scheme.
Full, incremental, differential describes types of backups, which are often used *within* a GFS scheme, but it does not define the GFS rotation schedule itself.
A GFS (Grandfather-Father-Son) backup solution is a data backup rotation scheme that organizes backups into a hierarchical structure, typically involving daily backups (Son), weekly or monthly backups (Father), and annual backups (Grandfather) to provide tiered retention periods for data recovery.
Full, partial, differential is not a standard GFS terminology; GFS refers to the rotational schedule and retention policy rather than specific backup types in this phrasing.
