I think the answer would be "because it's a good conductor" (3rd option) as a good conductor is a material that easily allows the flow of electricity.
The best material to be used as an electrical wiring is the one which is capable of carrying the electric current to its maximum efficiency. Copper is known as one of the best conductors of electricity because of its readily available electrons which require only a small energy to get excited and move in order to transmit electricity.
A good insulator stops the flow of electricity and hence option D is incorrect
Hence, option C is correct
When you build electrical circuits, you want to use the BEST CONDUCTOR to make the wires, so you won't lose too much energy in the wires.
The best conductor is Silver. But when you see what it costs, your heart sinks. You begin to think that maybe you can get along without the #1 BEST conductor; maybe the #2 best conductor will work.
The #2 best conductor is copper. People almost always make do with #2.
i think its c. amphipod
metamorphism is the change of minerals or geologic texture (distinct arrangement of minerals) in pre-existing rocks (protoliths), without the protolith melting into liquid magma (a solid-state change). the change occurs primarily due to heat, pressure, and the introduction of chemically active fluids. i hoped i !
