The question requires converting 475 milliliters to fluid ounces. To convert from milliliters to fluid ounces, identify the conversion factor between these two units. Using the conversion factor, 1 fluid ounce is approximately equal to 29.5735 milliliters. To find out how many fluid ounces are in 475 milliliters, you would perform the following calculation:

1. Divide the number of milliliters by the number of milliliters in one fluid ounce to convert from a smaller unit to a larger unit. So, you would calculate 475 milliliters ÷ 29.5735 milliliters per ounce.
2. This calculation gives you approximately 16.07 fluid ounces.
3. Round the result to the nearest whole number if required by the context. In this case, the answer is approximately 16 fluid ounces.

So, the amount needed to purify the canteen cup is closest to 16 fluid ounces (Option a).
