D. 464

To convert the units of capacity to fluid ounces, we need to first convert the gallons, quarts, and cups to ounces.

1 gallon = 128 fluid ounces
3 gallons = 3 * 128 = 384 fluid ounces

1 quart = 32 fluid ounces
2 quarts = 2 * 32 = 64 fluid ounces

1 cup = 8 fluid ounces
1 cup = 1 * 8 = 8 fluid ounces

Adding all the conversions together:
384 + 64 + 8 = 456 fluid ounces

Therefore, 3 gallons 2 quarts 1 cup is equal to 456 fluid ounces. So the answer is C. 456.
