The correct statements regarding DC (direct current) current are:
C. A high voltage current can be transformed into a low voltage current. D. A low voltage current can be transformed into a high voltage current.
However, the statement that is often most directly associated with the characteristics of DC is that it typically flows in one direction, unlike AC (alternating current) where electrons move back and forth.
Therefore, if you're looking for a single statement to be deemed most true regarding DC current, the most relevant statements that apply to the nature and transformation of voltage under direct current would be C and D.
Regarding option E, it's generally AC that is sent from power plants to homes for distribution, while DC may be used in certain applications and is often seen in batteries and electronic circuits.
