Solution

The correct option is A $K N a C_{4} H_{4} O_{6}$
Fehling's solution is always prepared fresh in the laboratory. It is made initially as two separate solutions, known as Fehling's A and Fehling's B. Fehling's A is a blue aqueous solution of copper(II) sulfate, while Fehling's B is a clear and colorless solution of aqueous potassium sodium tartrate i.e, $K N a C_{4} H_{4} O_{6}$ (also known as Rochelle salt) and a strong alkali (commonly sodium hydroxide).
