Its always depending on kvl.

According to Kirchoff's voltage law the algebraic sum of voltage sources and drops in a closed circuit must be equal to zero.

Summation equals to zero that's why answer is zero.

This happens because of KVL.

Very good @Richmond, the word algebraic sum should be added for this answer unless it is wrong answer @Vishal.

VS : Source voltage.
VD : Voltage drops.
VS = -VD.
So VS+VD = 0.
VD : Voltage drops.
VS = -VD.
So VS+VD = 0.

The question ought to be technical enough to prevent different answers. To me adding all the voltage drops and the source voltage gives twice the source voltage unless the word 'algebraic sum' is used. Engineers pay much attention to detail.

@pearl: KVL is Vs1+Vs2+....=VD
IF VD is negative then VS=-VD gives VS+VD cannot be equal to Zero
Thats Wrong..KVL says that Sum of INCOMING voltages is Equal to Outgoing
IF VD is negative then VS=-VD gives VS+VD cannot be equal to Zero
Thats Wrong..KVL says that Sum of INCOMING voltages is Equal to Outgoing

Voltage source have posiive polarities and drops will be considered negative so appling kvl sum will be 0.
