Melly, this is the solution:
Let's recall that:
• 1 pint = 2 cups
,• 1 cup= 0.25 quarts
,• 1 cup = 8 fluid ounces
Therefore,
• 4 pints = 8 cups (they are equivalent)
,• 8 cups = 2 quarts (they are equivalent)
,• 8 cups = 64 fluid ounces (they are equivalent)
The measurement that is not equivalent is B. 72 fl. oz.
