Marks: +1, -0

In the Wein Bridge oscillator circuit shown in figure, the bridge is balanced when

$\;{R_{3}}/{R_{4}} = \;{R_{1}}/{R_{2}},ω = \;{1}/{√{R_{1}C_{1}R_{2}C_{2}}}$
$\;{R_{2}}/{R_{1}} = \;{C_{2}}/{C_{1}},ω = \;{1}/{R_{1}C_{1}R_{2}C_{2}}$
$\;{R_{3}}/{R_{4}} = \;{R_{1}}/{R_{2}} + \;{C_{2}}/{C_{1}},ω = \;{1}/{√{R_{1}C_{1}R_{2}C_{2}}}$
$\;{R_{3}}/{R_{4}} + \;{R_{1}}/{R_{2}} = \;{C_{2}}/{C_{1}},ω = \;{1}/{R_{1}C_{1}R_{2}C_{2}}$
