Answer :

Turmeric is a natural indicator. Turmeric solution turns red, when it comes in contact with bases. It is not affected by acids and neutral substances.

Applying turmeric solution to the test tube, the results are:-

(1) test tube A (Hydrochloric acid): No , change will happen since turmeric is not affected by acids and HCL is a acid
(2) test tube B (sodium hydroxide): Yes , turmeric will change its color to red since sodium hydroxide is basic nature.
(3) test tube c (sugar solution) : NO, change will happen as sugar solution is neither basic nor acidic in nature 

Hence, we can only identify basic solution using turmeric as an indicator
