उत्तर
The correct option is (a).
Celsius and Fahrenheit temperatures are related in the following way:
C = `5/9"F" - 160/9`
Here, F = temperature in Fahrenheit
C = temperature in Celsius
If this equation is plotted on the graph, then the curve will be represented by curve 'a' lying in the fourth quadrant with slope 5/9.
