Which device is used to inspect inside hard-to-see spaces, often used for appliances?

• A. Endoscope
• B. Snorkel
• C. Borescope
• D. Periscope

Answer: (C)

A borescope is a slender, long viewing instrument with a camera and light at the tip that you can insert into tight spaces to see inside appliances, ducts, or machinery without taking things apart. This makes it ideal for inspecting areas that are hard to access, such as the interior of vent housings or small ducts, to check for lint buildup, blockages, or damage. An endoscope is similar in principle but is typically associated with medical or specialized industrial inspections, not the everyday appliance context. A periscope is designed to look around obstacles or from above, not to peer into narrow cavities. A snorkel is for breathing underwater, so it isn’t used for inspection at all.
