What type of kit includes gauze bandages and a signaling mirror?

The correct answer is a survival kit. A survival kit is specifically designed to provide essential medical supplies and tools intended to help individuals in emergency situations. It typically includes items such as gauze bandages for treating injuries and a signaling mirror to alert rescuers or signal for help.

While utility kits and secondary utility kits may contain useful items, they usually do not focus specifically on emergency preparedness like a survival kit. An ELT (Emergency Locator Transmitter) kit is also not aligned with the inclusion of medical supplies and signaling devices for personal survival in various situations. Thus, the inclusion of gauze bandages and a signaling mirror strongly correlates with the purpose and contents of a survival kit, making it the ideal choice.
