Solution

The correct option is B Ketoses, proteins
Seliwanoff test is used to distinguish ketoses from aldoses. On treatment with a concentrated acid, ketones are dehydrated more rapidly to give furfural derivative and on condensation with resorcinol give cherry red complex.

Positive Seliwanoff's test - Ketoses present

Positive Xanthoproteic test - Presence of aromatic amino acid

The Xanthoproteic reaction is a method that can be used to detect presence of protein soluble in a solution, using concentrated nitric acid.
