(c)

Interpretation Introduction

Interpretation:

The amino acids required for obtaining the given aldehyde and the compound responsible for purple coloration need to be identified.

Concept introduction:

Ninhydrin react with primary amines to give a purple colored product.  This is a qualitative and quantitative test.  The aldehyde is obtained as by-product.  The purple coloration is seen due to compound that has more conjugated systems.  The more conjugation is present in the system the more colored the compound will be.  The general scheme can be shown as,
