Correct answer

3

Step-by-step solution

Fehling's solution is prepared by combining two separate solutions. Fehling's A , which is a deep blue aqueous solution of copper II sulfate, and Fehling's B , which is a colourless solution of aqueous potassium sodium tartrate (also known as Rochelle salt) made strongly alkali with potassium hydroxide. The structure of Fehling's solution B is-
