Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Concept:
Electrical conductivity depends on free electron availability and scattering mechanisms.
Metals with highly mobile electrons have higher conductivity.
Step 1: Standard conductivity order.
Empirical ranking: \[ Ag > Cu > Au > Al > Pt \] Since copper is not given, comparison becomes: \[ Ag > Au > Al > Pt \]
Step 2: Interpretation.
Silver has highest conductivity due to:
• lowest resistivity
• high electron mobility Platinum has lowest among given due to high scattering. Final Answer: \[ \boxed{Silver > Gold > Aluminium > Platinum} \]
