It is simple to memory:
SIDE:
SI-(S)STAR CONNECTION (I)CURRENT SAME.
DE-(D)DELTA CONNECTION (E)VOLTAGE SAME.

In star connection
1. Line current=phase current
2. V-line=root3*V-phase
where as in delta connection quite opposite.

In a Star connection.
Current remains same but line voltage is root 3 times of phase voltage.
In a delta connection.
Voltage reamins same but line current is root 3 times of phase current.
Current remains same but line voltage is root 3 times of phase voltage.
In a delta connection.
Voltage reamins same but line current is root 3 times of phase current.

Consider star connection
Iph=Il / 3^1/2
Vph=vl
So the answer is A.
Iph=Il / 3^1/2
Vph=vl
So the answer is A.

In star connection phase current equal to line current so that Line voltage equal to root3 times phase voltage.

Where we can use star and delta connection?
Kishor said:

Delta connection are used transmission and star connection are used distribution line.

What exactly is this load current? Can understand line current and phase current?
Parth said:

Load current means the current appears across appliances (resistance).
Here line current is the current measure across transmission line and phase current is the current measure across the phase of star or delta connection.
Here line current is the current measure across transmission line and phase current is the current measure across the phase of star or delta connection.
