I'm sorry but this is the wrong answer.
Remember that each branch has the entire voltage across it.
Applying Ohm's law to the top branch:
I=V/R
=6/4 A
=1.5A
The lower branch has a combined resistance of 4Ω because the two resistirs are in series.
Applying Ohm's law to the bottom branch:
I=V/R
=6/(2+2) A
=1.5A
