I make use of kcl but not able to get ans.

Do oc of current and apply ohms law so current=31ma
and sc voltage source apply current divider rule then you obtain current=103.84ma
add both you get 134ma(approx).

Why we can't apply kcl. I think kcl make it eassy.

Use nodal analysis, you will get nearer value to option D.

0=V-12/270+V/120+150
V=16.15
current through R2
I=V/R
I=16.15/120
=134mA
V=16.15
current through R2
I=V/R
I=16.15/120
=134mA

Use of source transformation techniqu make will make the problem easy,120*0.15=18.00v will connected with series with 120 ohm resister and then apply kvl 120i+270i+18-12=-6/390

I1 = I2 - 0.150 ---- 1.
v = 270I1 + 120I2 ---- 2.
12 = 270(I2-0.150) + 120I2
I2 = (12+270*0.150)/390 = 134 mA.
v = 270I1 + 120I2 ---- 2.
12 = 270(I2-0.150) + 120I2
I2 = (12+270*0.150)/390 = 134 mA.

By using nodal analysis, we can easily get the final result 134 mA.

By using kvl, we can solve the easily final result 134.12.
