Answer: So, the answer is (A) low conductivity media.
Explanation:Resistance to current flow is lowest for materials with high conductivity.
Conductivity is the measure of a material's ability to conduct electricity. Materials with high conductivity have a low resistance to the flow of electrical current, while materials with low conductivity have a high resistance to the flow of electrical current.
The other options, such as small cross-sectional area media, long length of conductor, and high resistivity media, all increase resistance and make it harder for current to flow through the conductor. Short length of conductor may decrease resistance, but it is not as effective as using a material with high conductivity.
