Answer
The sentence can be completed with the words 'cloudy or milky'. So, "If fat is present, a mixture of ethanol and water becomes cloudy or milky in colour."
Explanation
Ethanol is an alcohol that can combine with both oily and watery substances. This question is asking what will happen to the colour of a mixture of ethanol water when fat is present. It is common knowledge in science that when ethanol and water are mixed with fat, the result is a cloudy (turbid) or milky solution. this occurs because fats do not dissolve in water, and the mixture of the two leads to an emulsion, displaying as a cloudy or milky substance
