Answer:
Between silver and aluminum wires of same thickness and length, silver will offer lesser resistance.
Explanation:
Aluminum will offer higher resistance than silver (both having same thickness and length).
Silver has lesser resistivity than aluminum.
Resistivity is directly proportional to resistance.
Thus, between to wires of distinct materials, one with higher resistivity will offer greater resistance.
