Match the Column-I (functioning of Daniel cell) with Column-II (value of \( \mathrm{E}_{\mathrm{ext}} \) ) and choose the correct option.
Column-I Column-II
(A) Flow of electrons from
(p) \( \mathrm{E}=1.1 \mathrm{~V} \)
\( \mathrm{Cu} \) to \( \mathrm{Zn} \) and current flows from \( \mathrm{Zn} \) to \( \mathrm{Cu} \)
(B) No flow of electrons
(q) \( \mathrm{E}1.1 \mathrm{~V} \) or current
(C) Zn dissolves at anode
(r) \( \mathrm{E}1.1 \mathrm{~V} \) and copper deposits at cathode
(a) \( (\mathrm{A})-(\mathrm{q}),(\mathrm{B})-(\mathrm{p}),(\mathrm{C})-(\mathrm{r}) \)
(b) \( (\mathrm{A})-(\mathrm{r}),(\mathrm{B})-(\mathrm{p}),(\mathrm{C})-(\mathrm{q}) \)
(c) \( (\mathrm{A})-(\mathrm{p}),(\mathrm{B})-(\mathrm{r}),(\mathrm{C})-(\mathrm{q}) \)
(d) \( (\mathrm{A})-(\mathrm{r}),(\mathrm{B})-(\mathrm{q}),(\mathrm{C})-(\mathrm{p}) \)
