The correct option is (B) 574.32.

Explanation:

Let temperature in Kelvin is K and in Fahrenheit is F 

Given K = F 

We know, 

K = [(5/9) (F – 32)] + 273 

Put K = F 

K = [(5/9) (K – 32)] + 273 

K = (5/9)K – {(5/9) × 32} + 273 

∴ (4/9)K = – 17.78 + 273 

∴ (4/9)K = 255.22 

∴ K = 574.24 

∴ Temperature is K = F = 574.24
