$A$ chemist has $4$ samples of artificial sweetener $A, B, C$,and $D$. To identify these samples,he performed certain experiments and noted the following observations:
$(i)$ $A$ and $D$ both form blue-violet colour with ninhydrin.
$(ii)$ Lassaigne extract of $C$ gives positive $AgNO_{3}$ test and negative $Fe_{4}[Fe(CN)_{6}]_{3}$ test.
$(iii)$ Lassaigne extract of $B$ and $D$ gives positive sodium nitroprusside test.
Based on these observations,which option is correct?

• A
  $A$: Aspartame; $B$: Saccharin; $C$: Sucralose; $D$: Alitame
• B
  $A$: Alitame; $B$: Saccharin; $C$: Aspartame; $D$: Sucralose
• C
  $A$: Saccharin; $B$: Alitame; $C$: Sucralose; $D$: Aspartame
• D
  $A$: Aspartame; $B$: Alitame; $C$: Saccharin; $D$: Sucralose
