The given voltage limit is the peak voltage (Vpeak) of the AC signal. To find the maximum RMS voltage that can be supplied, we need to use the following formula:

Vrms = Vpeak / sqrt(2)

Plugging in the given Vpeak value, we get:

Vrms = 11ea83ea_6abc_b7a4_aeff_cd3ed4c85f8d_TB6394_11 / sqrt(2)

Vrms = 6.665 V (rounded to three significant figures)

Therefore, the highest RMS voltage that can be supplied while staying below the voltage limit is 6.665 V, which is option A.
