The correct answer is A. 33 V.
The voltage across a resistor is equal to the current flowing through it multiplied by its resistance. In this case, the current is 2 A and the resistance is 33 Ω, so the voltage is 33 V.
Option B is incorrect because it is twice the actual voltage. Option C is incorrect because it is four times the actual voltage. Option D is incorrect because it is eight times the actual voltage.
