Answer:
Option A. is the correct option.
Step-by-step explanation:
In this question temperatures have been given in °C and °F and we have to arrange them from low to high.
For this we will change the temperatures from °C to °F first.

For 20°C

20°C = 56°F
For 36°C

36°C = 96.8 °F
Now we can easily arrange the temperatures as
56°F, 75°F, 94°F, 96.8°F Or 20°C, 75°F, 94°F, 36°C
Option A. is the correct option.
