A few engineering fields in the U.S. measure thermodynamic temperature using the Rankine scale.
The Rankine scale is one of the temperature scales used when an absolute temperature scale is needed. The Rankine scale is useful in calcluations of oil or gas present in an oil or gas reservoir (one of the factors in the equations is the ratio of standard temperature to formation temperature; generally add 460 to the temperature in degrees Fahrenheit to obtain degrees Rankine).
°R = degrees Rankine, this is the absolute temperature scale relative to the Fahrenheit scale. 0°R = -459.67°F the freezing point of water = 491.67°R°C = degrees Celsius (or Centigrade), this is the common metric temperature scale where the freezing point of water is 0°C and the boiling point is 100°CTo convert from°R to°C subtract 491.67° then multiply by 5/9 (0.555555....)To convert from°C to°R multiply by 1.8 then add 491.67°To convert from°R to°F subtract 459.67°
Option A (15°C) represents a different temperature scale compared to the other three options because it uses the Celsius scale, while the other three options use the Fahrenheit, Kelvin, and Rankine scales respectively.
Paris uses the Celsius temperature scale.
The centigrade or Celsius scale in which water freezes at 0 and boils at 100 degrees at sea level.

Kelvin and Rankine
The Rankine scale, like the Kelvin scale, establishes a zero point at "absolute zero", the theoretical minimum temperature of any matter. But the Rankine scale uses the same size "degree" as Fahrenheit, making zero degrees R = -459.67 °F. So in the four common scales, 0 R = -459.67 °F = 0 K = -273.15 °C.

Kelvin were 0 = absolute zero and uses Celsius as unit of measure Celsius Fahrenheit Those are the most common. There are a few more the most common is Rankine which is similar to Kelvin except it uses Fahrenheit as unit of measure
The Fahrenheit scale was traditionally used in the English system of measurement until largely supplanted by the Celsius scale. Measurements in the Fahrenheit scale are generally used only in the US, almost exclusively for air temperatures, body temperatures, and oven temperatures.Another scale that uses English degree units is the Rankine scale, which is based on absolute zero.
Option A (15°C) represents a different temperature scale compared to the other three options because it uses the Celsius scale, while the other three options use the Fahrenheit, Kelvin, and Rankine scales respectively.
The centigrade (aka Celsius) scale uses equal degrees of measurement.
Science does not use the Fahrenheit scale, it uses the Celsius scale or the Kelvin scale instead.
China primarily uses the Celsius temperature scale for weather forecasts and everyday temperature measurements. However, in some engineering and scientific applications, the Kelvin temperature scale is also used.
America primarily uses the Fahrenheit scale to measure temperature.
The Kelvin scale uses the abbreviation K. It is a unit of temperature measurement based on the thermodynamic temperature scale, in which 0 K represents absolute zero, the absence of all thermal energy.
