Homework Equations

$V = I R$

The Attempt at a Solution

Leaving 4 ohm above resistor Equivalent R will be
$R_{eq} = \frac{4*4}{4+4} + 4 + 1.6 = 7.6$
$I = \frac{V}{R}$
$I = \frac{4}{7.6} = 0.526$
Ans is not given in the option please tell what I'm doing wrong

Why do you think you can ignore the top resistor?

Also, note that the middle contraption is two 4 ohm resistors in parallel with a wire of resistance zero ...
