The line $A$ to neutral voltage is $10\angle 15^\circ$ for a balanced three phase star-connected load with phase sequence $ABC$. The voltage of line $B$ with respect to line $C$ is given by
- $10\sqrt{3}\angle 105^\circ$
- $10\angle 105^\circ$
- $10\sqrt{3}\angle -75^\circ$
- $-10\sqrt{3}\angle 90^\circ$
