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) \( \mathrm{A} \) and \( \mathrm{D} \) both form blue-violet colour with ninhydrin.

(ii) Lassaigne extract of \( \mathrm{C} \) gives positive \( \mathrm{AgNO}_{3} \) test and negative \( \mathrm{Fe}_{4}\left[\mathrm{Fe}(\mathrm{CN})_{6}\right]_{3} \) test.

(iii) Lassaigne extract of \( \mathrm{B} \) and \( \mathrm{D} \) gives positive sodium nitroprusside test.

Based on these observations which option is correct ?
