In a river, which of the following would most likely be carried by suspension?
"Minerals" is the one among the choices given in the question that would most likely be carried by suspension in a river. The correct option among all the options that are given in the question is the second option. I hope that this is the answer that you were looking for and it has actually helped you.
From a chemical point of view, suspensions are those where microscopically particles are dispersed throughout the liquid or gas with lesser densities. They are easily filtered out, but not easily settled. From the choices above, the answer would be sand as they cannot be dissolved in water and small enough to create suspension.
