\begin{array}{l}{\mathrm{1\: F}=1 \mathrm{\: Eq} \text { of } \mathrm{O}_{2}+1\: \mathrm{Eq} \text { of } \mathrm{H}_{2}} \\ {=5.6 \mathrm{\: L\: O}_{2}+11.2 \mathrm{\: L} \text { of } \mathrm{H}_{2}=16.8 \mathrm{\: L}}\end{array}
\begin{array}{l}{16.8 \times 10^{3} \mathrm{\: mL} \Rightarrow 1 \mathrm{\: F}} \\ {\begin{aligned} 504 \mathrm{\: mL} & \Rightarrow \frac{1 \times 504}{16.8 \times 10^{3}} \\=& 0.03 \mathrm{\: F}=0.03 \times 96500=2895 \mathrm{\: C} \end{aligned}}\end{array}

Therefore,option(1) is correct
