'A' and 'C' are saying exactly the same thing.
The correct choice is 'D'.
The complex impedance of a purely resistive circuit is purely real.
Since there is no reactance, there is no phase shift, so the power
factor is ' 1 ', KVA = KW, KVAR = 0, etc.

When an alternating voltage is applied to purely resistive circuit what happens?
When an alternating voltage is applied to a purely resistive circuit, the resulting current is in phase with the voltage.
Ac voltage applied across a load resistance produce alternating current?
The reason an AC voltage applied across a load resistance produces alternating current is because when you have AC voltage you have to have AC current. If DC voltage is applied, DC current is produced.
What happens when an alternating potential difference is applied across a primary coil of a transformer?
burn or burst
What is the power developed in a purely resistive circuit with 15volts rms applied and drawing 10 amps?
(15 volts) x (10 Amps) = 150 watts
What is the Difference between resistive and capacitive load?
when a resistive load is applied there is no phase angle difference between voltage and current. when a inductive load is applied there is phase difference between voltage and current. current lags voltage by an angle of 90 degrees for pure inductive load
When an alternating voltage is applied to purely resistive circuit what happens?

What is the applied voltage to a resistive capacitive circuit?
this is the amount of voltage a circuit can hold.
What is the science behind the alternating current?
When a sinusoidal alternating voltage is applied in a circuit, the resulting alternating current is also sinusoidal and has the same frequency as that of applied voltage .However, there is generally a phase difference between the applied voltage and the resulting current.This is how alternating-current circuit works.

What is single phase power factor meter?
Power Factor applies to all A.C.(alternating current) power supplies. It ma not be apparent when a purely resistive load is applied as this offers a PF of 1.0 but any other load type will have a power factor somewhere between 0.0 and 1.0.

Does a television run on alternating current?
The television runs on Direct current or DC. Though AC is applied, it is converted to DC and used by the television to operate.
How much is 8.8Kw in amps?
Kilowatss (kw) are a measure of power, not speed. The speed of an object with 8.2 kw of power applied to it is dependent on the mass of the object, the acceleration time, and any resistive friction forces.
What is construction and working of single phase transformer?
The single phase transformer works on the principle of mutual induction. Explanation: When an alternating voltage V1 is applied to a primary winding, an an alternating current I1 flows in it producing an alternating flux in the core. As per Faraday's law of electromagnetic induction, an emf e1 is induced in the primary winding. Where N1 is the number of the turns in the primary winding's induced emf in the primary winding is nearly equal and opposite to the applied voltage V1
