B Correct answer
Explanation

Silver is the best conductor of electricity among all metals, including copper. Silver has the highest electrical conductivity of any element - approximately 6.30×10^7 S/m, compared to copper's 5.96×10^7 S/m. The higher conductivity means silver offers less resistance to electrical current flow. Copper is commonly used instead due to silver's much higher cost, but silver remains the superior conductor. Iron (C) and zinc (D) have significantly lower conductivity.
