Solution

The correct option is C it will be a pure substance.
According to the law of constant composition or definite proportions, irrespective of the source of a chemical compound it is always found to be made of the same elements combined in the same fixed proportion by mass. Thus, according to the above law, it will be a pure substance because sugar obtained by different sources like dates and sugarcane will have the same chemical composition.
