previous question next question

Explanation:

A single - ladder is a basic type of ladder. An extension ladder's base section is similar in structure and function to a single - ladder as it is a non - extendable part of the extension ladder and has a similar build to a single ladder. The side rails are just part of the ladder structure, a step - ladder has a different design with a self - supporting A - frame, and the fly section of an extension ladder is the extendable part which is different from a single ladder.

Answer:

B. Extension Ladder’s Base Section
