In Y connection line voltage is 1.732 times of phase voltage.

Vab=Va-Vb IN STAR so phase of delta Vsorce=|Vab| bc & ca.
But line current is simply kcl across the node.

Delta connection Line volume = Phase volume and Star connection Line volume = 1/3 Phase volume.

Delta not equal to star.

If the delta connected source is fed to the star connected load then phase difference is 120'. So that difference will be same.

Load voltage e.g. phase voltage on load side which is connected in star and source is delta.
So line and phase volt is equal for this.
Now, V(source line) = Vr-Vy (load phase) depends on nomination R, Y, B.
So line and phase volt is equal for this.
Now, V(source line) = Vr-Vy (load phase) depends on nomination R, Y, B.

Tthe difference of the corresponding load voltage means:
Vab = Va - Vb.
So phase voltage is Vab.
The difference of load voltages is Va - Vb.
Vab = Va - Vb.
So phase voltage is Vab.
The difference of load voltages is Va - Vb.

It's C, not A because in delta there is 3 phase R, Y, & B.

The Common point of the Star Connection is called Neutral or Star Point. Consider VR, VB, VY are three-phase voltages and VRB, VBY, and VRY are line voltages:
|VR|=|VB|=|VY|=|VPhase|
Let VPhase= VP,
|VR|=|VB|=|VY|=|VP|
We can write VRY as,
VRY = VR + (-VY).
VRY = VR -VY.
|VR|=|VB|=|VY|=|VPhase|
Let VPhase= VP,
|VR|=|VB|=|VY|=|VP|
We can write VRY as,
VRY = VR + (-VY).
VRY = VR -VY.
