Answer:
The question seems to be confusingly composed and not relevant to the choices listed. Still, addressing the unrelated question regarding the type of current used in cars, the correct answer is 'direct current.'
Step-by-step explanation:
The question appears to be a chemistry question regarding the nature of current in various compounds, somewhat mixed with other unrelated parts. When looking for an answer that uses alternating current, none of the listed choices (NO₂¹, O₂₈, DO, H₂O) directly correspond to a use of electric currents, as they represent chemical species, not electrical concepts or devices.
However, if I had to correct the question and interpret the most relevant choice related to electrical current, the answer to what type of current is used in cars is c. direct current. Most cars use a 12-volt direct current (DC) electrical system for the battery and the rest of the electrical system.
Although, in the context of the alternating current, which is typically used in household appliances and is supplied by electrical power grids, none of the options is correct.
