Solution
The correct option is A Green
A Universal indicator is a pH indicator composed of a solution of several compounds that exhibits several smooth colour changes over a pH value range from 1-14 to indicate the acidity or alkalinity of solutions. It turns green in presence of a neutral compound. Raw cow's milk has neither acidic nor basic effect on body hence it is neutral. Thus, universal indicator turns green when mixed with raw cow's milk.
