Capacitor `C_(3)` in the circuit is variable capacitor (its capacitance can be varied). Graph is plotted between potential difference `V_(1)` (across capacitor `C_(1)`) versus `C_(3)`.
Electric potential `V_(1)` approaches on asymptote of 10 volts as `C_(3) to infty`
The ratio of energy stored in capacitor`C_(1)` to that of total energy when`C_(3) toinfty` is

Options

A. zero
B. 1/3
C. 1
D. Data insufficient
