168 ohms and 41.67v are correct.

@ALL.
For the kind information, R3 is opened while calculating Rth. So, actual Rth is 100+68. This is what the Venin's theorem states.

vth=(VS*R3)/(R1+R2+R3)
Rth=R1R2/(R1+R2)
Rth=R1R2/(R1+R2)

I want some simple technic for this sum.

rth = r3||(r1 + r2)
vth = vs.r3/r1+r2
vth = vs.r3/r1+r2

rth=120//(100+68)
vth=
vth = vs.r3/r1+r2
=ioo*120/(100+120+68)
vth=
vth = vs.r3/r1+r2
=ioo*120/(100+120+68)

Vth=v*120/288,
Rth=168*120/(120+168)
Rth=168*120/(120+168)

Vth = R3*(Vs/(R1+R2+R3))= 120*(100/(68+100+120)) = 41.67 V
Rth = R3//(R1+R2) = (120*160) / (120 + 168)= 70 ohm
Rth = R3//(R1+R2) = (120*160) / (120 + 168)= 70 ohm

From circuit
Vth=VR3/(R1+R2+R3);Rth=(R1+R2)//R3;
on solving ans is option D.
