Assertion: Long distance transmission of a.c. is carried out at extremely high voltages. Reason: Because when the distance is large, voltage has to be large. (A) If both assertion and reason are true and reason is the correct explanation of assertion (B) If both assertion and reason are true but reason is not the correct explanation of assertion (C) If assertion is true but reason is false (D) If both assertion and reason are false
