The diagram shows a capacitor C and a resistor R connected in series to an ac source.  V₁ and V₂  are voltmeters and A is an ammeter

Consider now the following statements

I.     Readings in A and V₂ are always in phase

II.    Reading in V₁ is ahead in phase with reading in V₂

III.  Readings in A and V₁ are always in phase which of these statements are/is correct         

• A

  I only

• B

  II only

• C

  I and II only

• D

  II and III only
