Hint:Bunsen burner is a gas burner used in the laboratory as a laboratory equipment. When a compound comes in contact with the Bunsen burner, it imparts colored flames. Bunsen burner is used to provide a single flame.

-Bunsen burner is used in the laboratory that produces single open gas flames. It is used for combustion and heating. The gas can be liquefied petroleum, for example, butane and propane, or it can be natural gas, which is mainly methane.
-When $NaCl$ is passed through this flame, it imparts yellow colouration to the Bunsen burner non – luminous flame. Therefore, option (A) is incorrect.
-When $BaC{{l}_{2}}$ is passed through this flame, it imparts green colouration to the Bunsen burner non – luminous flame. Therefore, option (B) is also incorrect.
-When $CaC{{l}_{2}}$ is passed through this flame, it imparts orange colouration to the Bunsen burner non – luminous flame. Therefore, option (C) is also incorrect.
-When $KCl$ is passed through this flame, it imparts violet colouration to the Bunsen burner non – luminous flame. Therefore, option (D) is correct.
-Hence, $KCl$ is the one that imparts violet colouration to the Bunsen burner non-luminous flame.
So, the correct option is (D) $KCl$ .

-In the conclusion, when the compound is passed through the Bunsen burner, they impart colored flames. In this question, violet color is imparted by the $KCl$ compound from the Bunsen burner.
