Final answer:
Copper is the best choice for repairing a break in an electrical circuit due to its superior conductivity and flexibility, making it ideal for a wide range of electrical applications.
Step-by-step explanation:
The best material for passing current from one part of an electrical circuit to another is Copper (A). Copper is highly regarded for its excellent conductivity and is widely used for this reason in various electrical applications. It is preferred over other materials like wood, rubber, and glass, which are insulators and do not effectively conduct electricity. Not only does copper's flexibility make it easy to handle and install, but it also allows for efficient electron flow through the wires, enabling a full range of electrical devices to operate as intended.
