You're on a roll — Step 1: Define resistivity and conductivity. Resistivity () is a measure of how strongly a material opposes the flow of electric current. Conductivity () is a measure of how easily electric current flows through a material. Step 2: State the relationship between resistivity and conductivity. Conductivity is the reciprocal of resistivity. = (1)/() Step 3: Calculate the product of resistivity and conductivity. The product of resistivity and conductivity is × . Substitute the relationship from Step 2 into the product: × = × ((1)/()) × = 1 The product of resistivity and conductivity is always 1. Step 4: Determine what the product depends on. Since the product is always 1, it is a constant and does not depend on any physical properties like cross-sectional area, temperature, or length. Comparing this with the given options: [A] अनुप्रस्थ परिच्छेद क्षेत्र (Cross-sectional area) [B] तापमान (Temperature) [C] लंबाई (Length) [D] इनमें से कोई नहीं (None of these) The product does not depend on options [A], [B], or [C]. Therefore, the correct answer is [D]. The final answer is D. What's next?
