Answer: Option (A) is the correct answer.
Explanation:
A heterogeneous mixture is a mixture in which the constituent particles are not uniformly distributed throughout the solution.
For example, a mixture of sand and water is a heterogeneous mixture because sand particles deposit at the bottom of water after sometime upon mixing.
Whereas sugar, baking soda, and salt are all soluble in water and their particles uniformly distribute into water. Hence, they form a homogeneous mixture.
Thus, we can conclude that sand and water would likely form a heterogeneous mixture.
