Given below is the set up for Daniell cell. Label p, q, r, s, t in the given figure.

Options

A. `{:(" p"," q"," r"," s"," t",),("Anode","Cathode","Salt","Electron","Current",),(,,"bridge","flow","flow",):}`
B. `{:(" p"," q"," r"," s"," t",),("Cathode","Anode","Salt","Current","Electron",),(,,"bridge","flow","flow",):}`
C. `{:(" p"," q"," r"," s"," t",),("Anode","Cathode","Salt","Current","Electron",),(,,"bridge","flow","flow",):}`
D. `{:(" p"," q"," r"," s"," t",),("Cathode","Anode","Salt","Ions","Electron",),(,,"bridge","flow","flow",):}`

Answer

A

Explanation

(p) At anode : oxidation takes place.
(q) At cathode : reduction takes place.
(r) Salt bridge for migration of ions.
(s) Electrons flow from anode to cathode.
Current flows from cathode to anode.
