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 value of C3 for which potential difference across `C_(1)` will become 8V, is

B. `2.5 C_(1)`
C. `3.5 C_(1)`
D. `4.5 C_(1)`

Answer
