Phasors and Phasor Diagrams

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  


In RC series circuit voltage across the capacitor lags the voltage across the resistance by   π2
