What is the freezing point of water in Rankine?

Explanation:
Rankine is an absolute temperature scale based on Fahrenheit, so to convert from Fahrenheit to Rankine you add 459.67. Water freezes at 32°F, which converts to 32 + 459.67 = 491.67 R. That’s why the correct value is 491.67. For context, 273.15 is the freezing point in Celsius, not Rankine; 0 in Rankine is absolute zero (-459.67°F); and 500.0 is simply a distractor.
