Answer: Option d is the correct answer.

Explanation:

Concept: A substance that permits electrons to pass through it with little impediment or resistance is said to be a good conductor of electricity. In other words, the simplest definition of an electrical conductor is a material that makes it simple for electricity to pass through it. A material is said to be a good conductor of electricity if, when compared to another type, it allows for a better flow of electricity. The other type of material is said to be a bad conductor. Metals are the most common conducting materials utilized in real-world applications. Silver, Copper, and Gold are some of the top metal conductors. A metal's conductivity increases with the number of free electrons it contains. In comparison to copper and gold, silver has better electrical conductivity. Copper is used in all home appliances and circuits because it is significantly less expensive than silver. There are certain non-metals that are excellent electrical conductors. For instance, graphite, which is made of carbon, is a particularly effective conductor of electricity. Ionic conductors are conductors that exist in solution form as an ionic solution and effective conductor of electricity, saltwater is one example. Despite having inferior electrical conductivity compared to conductors, semiconductors nonetheless have their applications. Germanium (Ge) and silicon are a few of examples of semiconductors (Si). A substance known as a superconductor conducts electricity and offers no resistance to the flow of electrons. The Dutch physicist Heike Kamerlingh Onnes made the discovery of the superconductivity phenomena in 1911. When chilled below a specific threshold temperature, certain elements or metallic alloys lose their electrical resistance property and turn into superconductors. Superconductors made of niobium, cuprate, magnesium, and diboride are among the best. Resistance is the opposite of conductivity. High levels of resistance prevent electrons from passing through insulators. Typical insulator types include wood, rubber, glass, plastic, and air.

Step 1: from the above definition , good electronic conductor is the one that has few electrons.

Note: Other options are incorrect since they may or may not be always made of copper, should never have low conductance, never produces a voltage droppage.

Final ans: So, here a good electronic conductor is one that,

  1. have free electrons which can flow through the atom and can make it charged.
