Answer:

The answer is (approximately) A) #261^@"F"#.

Explanation:

The conversion factor for going from Kelvin to degrees Fahrenheit looks like this:

#T_(""^@"F") = 9/5 * T_(""^@"K") - 459.67#

So, in your case, a temperature of 400 K would correspond to

#T_(""^@"F") = 9/5 * 400 - 459.67 = 260.33""^@"F"#

So I assume that option (A) is the closest to this value.
