Define homogeneous mixture

A homogeneous mixture has a uniform composition throughout, where individual components are not visually distinguishable.

Evaluate the given options

• A) oil and water: Forms two distinct layers (heterogeneous).
• B) salt and pepper: Individual grains remain visible and separate (heterogeneous).
• C) sawdust and nails: Solid components remain distinct and easily separated (heterogeneous).
• D) salt in water: Salt dissolves completely to form a single, uniform liquid phase (homogeneous).

Identify the correct option

Option D represents a homogeneous mixture.
