Solution

The correct option is B $20 W, 8 w, 12 w$
$\begin{matrix} i = \frac{6}{3} = 2 A P o w e r p l i e d b y 10 V = 10 \times 2 = 20 W P o w e r c o n s u m e d b y 4 v = 4 \times 2 = 8 W & p o w e r d i s s i p u t e d b y 3 Ω r e s i s tan c e = i^{2} R = 12 W \end{matrix}$
Hence,
option $B$ is correct answer.
