Formula from physics to get the answer.
D is the best answer. In many physics problems we treat an extended object as if it were a point with the same mass located at the center of mass.
P = U × I
I = P / U = 1600W / 120V = 13.4A
P = 240V × 13.4A = 3216W
If your hair blower isnt rated for 220- 230V(this is the voltage in EU) you are most likely going to burn it.
