Answer: Option (B) is the correct answer.
Explanation:
A salt bridge in an electrochemical cell helps in maintaining the electrical neutrality at both reduction and oxidation half cells. It helps in the flow of electric current by maintaining the neutrality of the ions.
Similarly, in a dry cell the paste acts as an electrolyte which helps in the flow of electric current.
Thus, we can conclude that paste is the parts of a dry cell corresponds to the salt bridge shown in the diagram.
