Explanation:

We often refer to the electricity at a typical household outlet as being 120 V. In fact, the voltage of this AC source varies; the 120 V is "the rms value of the voltage".

The rms value of voltage is given by :

[tex]V_{rms}=\dfrac{V_{pk}}{\sqrt{2}}[/tex]

Where

[tex]v_{pk}[/tex] is the peak value of voltage

So, the correct option is (d). " rms value of voltage".
