Help: Which Content-Type header is/are correct? Help needed to figure out where am I doing it wrong?

fetch (url, {
method: ‘post’,
headers: {
“Content-type”: -------------
body: ‘foo=bar & lorem=ipsum’

After considering the snippet above which of the following values for the Content-Type header is/are correct?

A) application/x-www-form-urlencoded; charset=UTF-8
B) text/html; charset=utf-8
C)application/json; charset=UTF-8
D)Content-Type: multipart/form-data; boundry=something

According to me B and D is correct but the test is failing me. Any suggestions?

Hello there,

I would also put B. But what tests are you referring to?
