hello there! the answer is d. the united states.

if you grew up in the usa (which i'd assume, but i believe is also open to other countries) you grew up using fahrenheit. common things like this are setting the oven to 350 degrees fahrenheit, or knowing that the average body temperature is 98.6 degrees fahrenheit. well, like other countries listed, brazil, france and england all use celsius instead of fahrenheit. for example, 350 degrees for an oven would be 177 degrees celsius, or the average body temperature is 37 degrees celsius.

i hope this and have a great day!
