Answer 1

Let us take:

R1-3.000 R2-4.00 Ω R3-20.0 Ω Rs 9.00 Ω Rs 6.00 Ω 1,50 A

are in series. Their equivalent resistance is,

R2, Re

$R'=R_2+R_6=10.0\ \Omega$

This resistance is in parallel with $R_4$ and $R_5$.

Their equivalent resistance is,

R4R5R'

This resistance is in series with $R_1$. Then, their effective resistance is,

R", = R1 + R" = 5.98 Ω

This resistance is in parallel with $R_3$. Therefore, equivalent resistance of the circuit is,

R,"Rs 4.60 Ω

Then, required voltage is,

Most appropriate answer is option C.
