Here the question is mentioned only for sum voltage drop.

Answer should be B,
As Sum of the voltage drop and the voltage source is equal to zero.(Kirchhoff's voltage law), But in? only sum of voltage drop has mentioned.
As Sum of the voltage drop and the voltage source is equal to zero.(Kirchhoff's voltage law), But in? only sum of voltage drop has mentioned.

In the question they only mentioned sum of the voltage drop is zero which is false. Because according to kirchhoff's law algebraic sum of voltage drops which means voltage drop in passive elements and voltage supplied by sources sum is equal to zero.

According To kvl low its true.

According to KVL, it's FALSE, sum of voltage drops is equal to the sum of the voltage source. Vs = IR1 +IR2 + IR3. IRn.

The sum of all the voltage drops around a single closed loop in a circuit is zero. Here close loop has mentioned. So answer will be zero. If mentioned open loop, then answer will be supply voltage.
