Which of the following tools is specifically used to remove a module from an electronic assembly?

The chip puller is the tool specifically designed for the purpose of removing modules from electronic assemblies. It is engineered to securely grasp and pull integrated circuits or chips from their sockets without damaging either the chip or the circuit board. This is particularly important in electronics, where damage to sensitive components can affect functionality and performance.

The wire gauge measures the diameter of electrical wires, which is unrelated to module removal. The hydrometer is used to measure the specific gravity of liquids, typically for batteries, and does not have a function in electronic assembly. The cable stripper, on the other hand, is used for removing insulation from electrical cables, but it too does not pertain to the removal of electronic modules. Thus, the chip puller's specialized design and function make it the appropriate choice for this task.
