Need some help on a review question. The questions says: Andrew bought a fish tank to keep in his bedroom. Which is the most reasonable ESTIMATE for the capacity of the fish tank that Andrew bought?

a. 20 fl oz

b. 20 cups

c. 20 pints

d. 20 gallons

I'm pretty sure it isn't a or b. I'm having trouble deciding between c and d. Don't know much about fish tanks and the sizes they come in. Thanks..
