at first let analyze the given problem.
almirol known as "the combination of starch and water" for the final rinse of blankets and pants to make them stiff upon drying. so, almirol is kind of heterogeneous mixture because the substance remain physically separate. "starch that is combined to water is a heterogeneous"
most of all it is not a coarse mixture. suspension consists of an insoluble substance dispersed in a liquid. " almirol is not a suspension either"
Colloid the beam of light can be seen as it passes through the mixture. the particle are so small enough than the particle of solution. "so it's not a solution either" " the starch and water" this means that the colloid passed through the filter.
for me my answer is letter B, Colloid , Almirol is a colloid mixture.
