In Group I occupancies (such as hospitals, nursing homes, and correctional facilities), keys necessary for unlocking exit doors must be individually identifiable by both sight and touch. This ensures quick identification of keys in an emergency, especially for staff members assisting occupants with limited mobility.
Reference to Fire Inspector Documentation:
1. 2021 International Fire Code (IFC) – Section 1010.1.9.9 (Identifiable Keys for Exit Doors in Group I Occupancies)
IFC 1010.1.9.9 specifically states that in Group I occupancies, all keys used to unlock exit doors must be uniquely identifiable by both sight and touch.
This helps staff quickly locate and use the correct key in an emergency evacuation.
2. NFPA 101 – Life Safety Code (2021 Edition) – Section 18.2.2.2.6 (Key Identification in Institutional Occupancies)
NFPA 101 mandates that keys in healthcare and correctional facilities (Group I) must be distinguishable by touch and sight for emergency use.

Thus, the correct and verified answer is: C. Group I occupancies.
