Which ladder length corresponds to an extension ladder?

• A. 10 Ft Attic
• B. 14 Ft Roof
• C. 24 Ft Extension
• D. 20 Ft Extension

Answer: (C)

An extension ladder is a ladder with sliding sections that let you reach higher points, and it is identified by being described as an extension with a specific length. Attic ladders are fixed-length ladders for attic access, and roof ladders are sized for roof work and aren’t intended to extend in the same way.

The best match is the option described as a 24 ft extension ladder. It explicitly names itself as an extension ladder and gives the extended length, which is how extension ladders are categorized and selected for reach. The other choices describe different ladder types (attic or roof) or, while another extension option exists, the 24 ft extension is the one marked as an extension ladder in this context.
