Final answer:
The most active metal is zinc (Zn), followed by copper (Cu), and the least active is silver (Ag). The correct answer to arrange Cu, Ag, and Zn with the most active first is d) Zn, Cu, Ag, based on The Activity Series.
Step-by-step explanation:
The question at hand involves arranging the metals copper (Cu), silver (Ag), and zinc (Zn) in order of their reactivity based on The Activity Series, with the most active first. Using The Activity Series, which is a chart that lists metals according to their relative reactivity, we can determine that zinc is more reactive than copper and silver because it can be oxidized more easily. Metallic zinc will react with both copper and silver salts, while copper will not react with zinc ions, and by extension, silver is less reactive than copper.
Therefore, the correct arrangement from the most active to the least active metal is: Zn, Cu, Ag. So, the correct answer to the student's question is option d) Zn, Cu, Ag.
