In the following circuits shown in figure,

(d).

Explanation: Power produced in case $(i)$

$=\frac{\mathrm{V}^{2}}{\mathrm{R}}=\frac{144}{2}=77 \mathrm{~J} \mathrm{~s}^{-1}$

Power produced in case $(i i)=\frac{\mathrm{V}^{2}}{\mathrm{R}}=\frac{144}{4}=36 \mathrm{Js}^{-1}$

Power produced in case (iii) $=\frac{\mathrm{V}^{2}}{\mathrm{R}}=\frac{144}{1}=144 \mathrm{Js}^{-1}$
