Solution

The correct option is C Assertion is correct but Reason is incorrect
In electrochemical series, Lithium is the placed at bottom which is having lowest reduction potential and which tells that lithium is stable in its oxidised form and is weakest oxidising agent.
Lithium has the lowest electrode potential indicating that lithium ion is the weakest oxidising agent while lithium metal is the most powerful reducing agent in an aqueous solution.
Hence, Assertion is correct but Reason is incorrect.
