o cu
o li
o sb

Explanation:

Among the options, copper (Cu) is well - known for its high electrical conductivity. Aluminum (Al) also conducts electricity but not as well as copper. Lithium (Li) and antimony (Sb) are not as commonly used for enhancing electrical conductivity in alloys compared to copper.
