Answer:

I = 1.7 A.

Explanation:

According to Kirchhof's Current law/Node Law,

Sum of entering current = Sum of leaving current.

At, first junction, Entering current = 2 A + 2 A = 4 A.

At Second junction, Leaving current = 1 A + x A.

Since, Sum of entering current = Sum of leaving current,

1 A + x A = 4 A.

x= 3 A.

Now, at third junction, 3 A current divides into 1.3 A and I A.

Therefore, According to node law,

3 A = 1.3 A + I A.

I = 3 - 1.3

I = 1.7 A.

Therefore, 1.7 A (option A) is the right answer.
