Question

a fish tape is used to
pull wires through a wall or conduit.
measure the distance between two points.
push wires through a wall or conduit.
ensure level piping installations.

Explanation:

A fish tape is a tool used in electrical work. Its primary function is to pull wires through walls or conduits (not push, as it's a flexible tape that is fed in and then used to pull the wire). Measuring distance is done by tools like a tape measure, and ensuring level piping is done by a level tool. So the correct option is the one about pulling wires through a wall or conduit.

Answer:

A. pull wires through a wall or conduit.
