Which one is true solution:

• a.) Sugar sol
• b.) Blood
• c.) Starch
• d.) Ink

To determine which option is a true solution, we need to understand what a true solution is. A true solution is a homogeneous mixture where the solute is completely dissolved in the solvent, resulting in a clear liquid.

Analyzing the Options

• Sugar solution: When sugar is dissolved in water, it forms a clear solution. This is a true solution.
• Blood: Blood is a complex mixture containing cells, proteins, and other substances, making it a suspension rather than a true solution.
• Starch: Starch does not dissolve in water to form a true solution; instead, it forms a colloidal suspension.
• Ink: Ink can be a mixture of dyes and solvents, but it is not a true solution in the strictest sense.

Final Answer

The correct answer is Sugar solution, as it is the only option that qualifies as a true solution.
