[A]. 1 A
[B]. 7 A

Since KCL states that sum of incoming current is equal to sum outgoing current in a junction.

Consider a two resistances in parallel. If 4 A is flowing through one of the resistors and another 3 A to other resistor, then applying kcl to the circuit the sum of incoming current will be the outgoing current.

Hence 3+4 = 7 which is the correct answer.

This is any who is impressed with year answers ad very happy such a lovely website.

It is related with KCL which states that sum of incoming current is equal to sum outgoing current in a junction.

See, current is the flow of electrons means it's not generated into any junction what is comes in must comes out this is actually KCL.

So 3+4=7.
