Question

each cable is made of either gold, copper, or rubber. melanie also tests a glass rod, a steel rod, and a plastic rod. which group lists only items that will conduct electricity? gold cable, steel rod, rubber cable gold cable, steel rod, copper cable rubber cable, glass rod, plastic rod rubber cable, copper cable, plastic rod

Explanation:

To determine which items conduct electricity, we recall that metals (like gold, copper, steel) are good conductors, while non - metals/insulators (rubber, glass, plastic) do not conduct well. Gold cable (gold is metal), steel rod (steel is metal), and copper cable (copper is metal) are all conductors. The other options include insulators (rubber, glass, plastic) which do not conduct electricity.

Answer:

B. gold cable, steel rod, copper cable (assuming the option with this text is labeled as B; if the original question had labels like A, B, C, D, adjust the label as per the actual question's numbering. Since in the given image, the correct option is the one with "gold cable, steel rod, copper cable", we present it as the answer.)
