The question is incomplete, the complete question is;

Which statement describes a mixture of sand and

water at room temperature?

(1) It is heterogeneous, and its components are  in the same phase.

(2) It is heterogeneous, and its components are  in different phases.

(3) It is homogeneous, and its components are in  the same phase.

(4) It is homogeneous, and its components are in  different phases.

A mixture is any combination of substances which are not chemically combined together. The constituents of a mixture still retain their individual properties.

A mixture may be;

Since water and sand are in different phases at room temperature, the mixture is a heterogeneous mixture. Water is liquid and sand is solid.
