Three capacitors $C_1, C_2$, and $C_3$, whose values are $10\mu F, 5\mu F$, and $2\mu F$ respectively, have breakdown voltages of $10V$, $5V$, and $12V$ respectively. For the interconnection shown, the maximum safe voltage in Volts that can be applied across the combination and the corresponding total charge in $\mu C$ stored in the effective capacitance across the terminals are respectively
- $2.8$and $36$
- $7$ and $19$
- $2.8$ and $32$
- $7$ and $80$
