B Correct answer
Explanation

Sugar and milk forms a homogeneous mixture because sugar completely dissolves in milk, creating a uniform solution where you cannot see separate components or distinguish sugar particles from milk. The other options are heterogeneous: sand in water settles, sugar and sand remain as separate visible particles, and rice in water shows distinct solid particles in liquid.
