The correct option is A sand
Compound - It is a pure substance made by a chemical reaction of two or more elements in a fixed proportion.
For example -common salt, sugar, water, etc. are compounds.
The explanation for the correct answer - (A) Sand
Sand is not a compound. It is a mixture made up of fine soil particles in different proportions.
Mixture - When two or more substances are mixed physically in any variable proportion in such a way that they retain their individual properties is called a mixture.
The explanation for the incorrect answer -
(B) Water - water is a compound made up of hydrogen(H) and oxygen(O) in the ratio of 2:1.
(C) Sugar - sugar is a compound made by plants during photosynthesis from carbon dioxide and water in presence of sunlight.
