The argument tells us that cats eat fewer ounces per day of canned food versus dry food, but it costs more per day to feed a cat canned food. Which of the following can be properly inferred?

We can conclude from these facts that canned food must cost more per ounce (E), otherwise it would be mathematically impossible that the cost of canned food per day is higher, but the amount of ounces consumed is lower. The reason (D) is incorrect is because it leaves open a possibility that the cost is equal - "it costs no less to feed a cat that eats fewer ounces" implies that it could cost the same or more, whereas the argument clearly tells us that the cost of canned food per day is more than dry food.

Let me know if you have any further questions.
