Is my TMA marked correctly???? Discussion ThreadIs my TMA marked correctly???? Electrical Advice

I have the results of my Tutor marked assignment (TMA) back today and i had one question wrong but i dont think it is.

Q- An electric lamp has a filament resistance of 534 ohms. when connected to a 230v supply, the current flowing would be?
A-122820
B-0.4307
C-4.307
D-2.322

I achieved my answer by using ohms law. I used, I= R/V
534 / 230 = 2.321739130434783

My answer was and is D but my tutor maked it as incorrect and the correct answer being B ????????????????
