The correct answer is c.

Because ounce is a measuring unit of mass. To contrast this:

Cup. It's a US unit of volume. It is common to use this unit with cooking and serving sizes.

Gallon. It's also a unit of volume. This is a unit of measurement for liquid in both the US customary units and the British Imperial.

Ounce. It's also a unit of volume. It's a SI accepted Metric System.

Answer:          

Option c - ounce is the right answer.            

Step-by-step explanation:                    

Ounce is the correct answer.

Ounce is a measuring unit of mass or weight.                                    

Rest all options - cup, gallon and liter are an SI accepted metric system unit of volumes. In a standard form, a US Cup is 240 ml. U.S. standard gallon is equal to 231 cubic inches. The liter is used to measure volume of liquid.
