Option B
Zinc is the solvent iron is the solute
Step-by-step explanation:
A solvent is a material in which another substance dissolves.
while a solute is a material which is has dissolved in a solvent

In this case. to determine the metal which is acting as the solvent or solute, we will make use of their percentage abundance in the solution.
In most solutions that are not yet saturated, the common occurrence is that the quantity of the solvent is a lot more than the quantity of the solute.
From the question, we can see that 75% of the solution is made up of Zinc while 25% is made up of iron. This means that Zinc is the solvent while iron is the solute, because iron is dissolved in Zinc
