A Correct answer
Explanation

When sugar is added to water and a mixture of these two is formed, it suffers from lowering in freezing point and the freezing point of water is lowered and hence the first solid which separates out is ice. It is one of the colligative properties of a solution which is subjected to a change by the addition of solute.
