Answer : The correct option is, homogeneous mixtures
Explanation :
True solution : It is a homogeneous mixture in which the two or more substance is dissolved in the solution. The particle size is between 0.1 nm to 1 nm, then the solution is considered as a true solution.
Colloid : It is solution in which the one substance is insoluble in another solution that means the insoluble substance rotating in the solution. The particle size is between 2 to 1000 nm, then the solution is considered as a colloid.
Suspension : It is solution in which the one substance is insoluble in another solution that means the insoluble substance is sedimented into the solution. It is a heterogeneous mixture. The particle size is greater than 1000 nm, then the solution is considered as a suspension.
Heterogeneous mixtures : It is a mixture that appears non-uniformly throughout the solution and the particle size or shapes are also different.
Homogeneous mixtures : It is a mixture that appears uniformly throughout the solution and the particle size or shapes are not different.
Hence, all solutions are homogeneous mixtures.
