I think it is option (C).
If the answer is helpful then mark me as brainly.
C.) Wristwatch uses DC current to operate..
Resistance can be calculated by Ohm's law
As per ohm's law we will have

here we will have
voltage = 220 volts
current = 10 A
So by the above formula we will have


So resistance of the bulb is 22 ohm.
