Answer

Answer:

B. There can only be one voltage supplied.

Brief Explanations:

In DC current, the voltage source has a fixed polarity and typically provides a single - valued voltage. Electrons in DC move in one direction (not back - and - forth as in AC, so A is wrong). Transformers work on the principle of electromagnetic induction which requires changing magnetic fields and thus work with AC, not DC, so C and D are wrong. Power plants send AC to homes, not DC, so E is wrong.
