Understand that the size of a degree on a temperature scale refers to the magnitude of one unit increment on that scale.
Recall the size of degrees for common temperature scales: Celsius and Kelvin degrees are the same size, Fahrenheit degrees are smaller, and Rankine degrees are the same size as Fahrenheit degrees but shifted in zero point.
Note that 1 degree Celsius (or Kelvin) corresponds to a larger temperature change than 1 degree Fahrenheit or Rankine.
Compare the degree sizes: 1 degree Celsius = 1.8 degrees Fahrenheit, meaning Fahrenheit degrees are smaller than Celsius or Kelvin degrees.
Conclude that the Fahrenheit scale has the smallest sized degrees among the given options.
