There are some missing details in the options given, but we can solve the problem anyway.
In fact, the formula for the electric power is
[tex]P=I^2 R[/tex]
where I is the current and R the resistance, while Ohm's law states that
[tex]I= \frac{V}{R} [/tex]
where V is the voltage. So, if we replace the current I in the first equation by using Ohm's law, we can write the power using only voltage V and resistance R:
[tex]P= (\frac{V}{R})^2 R= \frac{V^2}{R} [/tex]
