Explanation:

3.01)

A circuit is a path where an electric current can flow, so we match "circuit" with option B.

A conductor is a material that lets electricity pass through, so we match "conductor" with option E.

An insulator is a material that does not let electricity pass through, so we match "insulator" with option D.

Answer:

B. a path where an electric current can flow
