Two ideal batteries of \( \mathrm{emf}_{1} \) and \( \mathrm{V}_{2} \) and three resistances
W \( R_{1}, R_{2} \) and \( R_{3} \) are connected as shown in the figure. The current in resistance \( R_{2} \) would be zero if

(a) \( \mathrm{V}_{1}=\mathrm{V}_{2} \) and \( \mathrm{R}_{1}=\mathrm{R}_{2}=\mathrm{R}_{3} \)
(b) \( \mathrm{V}_{1}=\mathrm{V}_{2} \) and \( \mathrm{R}_{1}=2 \mathrm{R}_{2}=\mathrm{R}_{3} \)
(c) \( \mathrm{V}_{1}=2 \mathrm{~V}_{2} \) and \( 2 \mathrm{R}_{1}=2 \mathrm{R}_{2}=\mathrm{R}_{3} \)
(d) \( 2 \mathrm{~V}_{1}=\mathrm{V}_{2} \) and \( 2 \mathrm{R}_{1}=\mathrm{R}_{2}=\mathrm{R}_{3} \)
