Solution

The correct option is B

An explanation for the correct option:
In the test tube, B its been given two compounds $K C l and A g N O_{3}$ .
The reaction between these two will be, $\underset{(P o t a s s i u m c h l o r i d e)}{\underset{⏟}{K C l (a q)}} + \underset{(S i l v e r n i t r a t e)}{\underset{⏟}{A g N O_{3} (a q)}} \to \underset{W h i t e p r e c i p i t a t e}{\underset{⏟}{\underset{(S i l v e r c h l o r i d e)}{\underset{⏟}{A g C l (s)}}}} ↓ + \underset{(P o t a s s i u m n i t r a t e)}{\underset{⏟}{K N O_{3} (a q)}}$
An explanation for the incorrect options:
In test-tube A, the reaction would be $\underset{(P o t a s s i u m i o d i d e)}{\underset{⏟}{K I (a q)}} + \underset{(S i l v e r n i t r a t e)}{\underset{⏟}{A g N O_{3} (a q)}} \to \underset{Y e l l o w p r e c i p i t a t e}{\underset{⏟}{\underset{(S i l v e r i o d i d e)}{\underset{⏟}{A g I (s)}} ↓}} + \underset{(P o t a s s i u m n i t r a t e)}{\underset{⏟}{K N O_{3} (a q)}}$ , hence option A is incorrect.
In test-tube C, the reaction would be $\underset{(S o d i u m h y d r o x i d e)}{\underset{⏟}{N a O H (a q)}} + \underset{(C o p p e r s u l p h a t e)}{\underset{⏟}{C u S O_{4} (a q)}} \to \underset{(C o p p e r h y d r o x i d e)}{\underset{⏟}{C u {(O H)}_{2} (a q)}} + \underset{(S o d i u m s u l p h a t e)}{\underset{⏟}{N a_{2} S O_{4} (a q)}}$ , no precipitate is formed, hence Option C is incorrect.
In test-tube D, the reaction would be $\underset{(C a l c i u m h y d r o x i d e)}{\underset{⏟}{C a {(O H)}_{2} (a q)}} + \underset{(C a r b o n d i o x i d e)}{\underset{⏟}{C O_{2} (g)}} \to \underset{(C a l c i u m c a r b o n a t e)}{\underset{⏟}{C a C O_{3} (s)}} + \underset{(W a t e r)}{\underset{⏟}{H_{2} O (l)}}$ no precipitate is formed, hence Option D is incorrect.
Hence, option B is the correct option.
