Two electrolytic cells, A containing aqueous $\mathrm{AgNO}{}_3$ and B containing aqueous $\mathrm{CuSO}{}_4$, are connected in parallel across a battery. The total current is $3.25\mathrm{A}$ and it flows for $3860\mathrm{s}$. Cell A deposits $5.40\mathrm{g}$ of silver. Take Ag = 108, Cu = 63.5, $F=96500\mathrm{C}\mathrm{mo}{\mathrm{l}}^{-1}$ and 100% efficiency. Which statements are correct?

1. AHad the same two cells been connected in series carrying $3.25\mathrm{A}$ for $3860\mathrm{s}$, cell B would deposit $8.26\mathrm{g}$ of copper
2. BThe current through cell A is $1.25\mathrm{A}$
3. CThe charge passed through cell B is $7720\mathrm{C}$
4. DThe mass of copper deposited in cell B is $2.54\mathrm{g}$
