Detailed Solution

Concept- Use the idea that a material is a bad conductor of electricity in this question. There aren't any unbound electrons or unbound charges that might flow across the lattice. Select the alternative that doesn't include free electrons. As a result, you'll obtain the proper response.
Insulators are substances that conduct electricity poorly.
Wood, glass, plastics, and non-metal components made of hydrocarbon polymers are a few examples.
Because the particles and their electrons are trapped inside a solid structure, charges cannot pass through them, which is why they do not conduct electricity.
Therefore, among the following choices, metals that are good electrical conductors are aluminum, silver, and copper.
Pure water is the only alternative left, but it is a poor conductor because its molecules lack free electrons, which allow current to flow as they move.
But always keep in mind that unclean or salty water is an excellent conductor of electricity.
So, this is the appropriate response.
Hence, the correct option is 3.
