C Correct answer
Explanation

Aluminium is used in microprocessors for interconnects due to its excellent balance of conductivity, reliability, and cost-effectiveness. While copper has better conductivity, aluminium's lower tendency to electromigration and established deposition processes made it the industry standard for decades until copper's adoption in the 1990s.
