Answer: b. heterogeneous mixture
Explanation:-
Heterogeneous mixtures : It is a mixture that has non-uniform distribution throughout the solution and thus there is a distinct boundary between the dispersed phase and dispersion medium. Example: sand in water
Homogeneous mixtures : It is a mixture that has uniformly throughout the solution and thus there is no distinct boundary between the dispersed phase and dispersion medium. Example: Salt in water
Thus Tossed salad in which the components are uniformly distributed and can be seen distinctly is a heterogeneous mixture.
