The inside of your refrigerator might be set to a temperature of about

A) -2.9°C
B) 29°C
C) 2.9°C
D) 43.5°C

I think the answer is C because that would put the temp in the 30's.

-2.9 C is below freezing, hard to pour the milk

29 C is above room temp (around 20 C)

2.9 C is above freezing but cold, good

43.5 C is half way to boiling, very warm
