Explanation:

Step1: Calculate price per apple for each store

For Store A: $\frac{1.20}{2}=0.60$ dollars per apple.
For Store B: $\frac{1.65}{3}=0.55$ dollars per apple.
For Store C: $\frac{3.20}{8}=0.40$ dollars per apple.
For Store D: $\frac{5.40}{12}=0.45$ dollars per apple.

Step2: Check option C

If we want to buy 24 apples:
For Store A: $24\div2 = 12$ sets, cost is $12\times1.20=14.40$ dollars.
For Store B: $24\div3 = 8$ sets, cost is $8\times1.65 = 13.20$ dollars.
For Store C: $24\div8=3$ sets, cost is $3\times3.20 = 9.60$ dollars.
For Store D: $24\div12 = 2$ sets, cost is $2\times5.40=10.80$ dollars.

Answer:

C. Store C has the lowest price per apple because purchasing exactly 24 apples from each store will cost Cathy the least amount at store C.
