So, I did some research and found that the other part of the question was, "A. Gasoline B. Blood C. Mud"
A suspension is a mixture containing solid particles that are large for sedimentation. We know that mud contains solid pieces of dirt that haven't been broken down. So, suspension = mud.
A solution is a mixture composed of two or more substances. We know that gasoline is made of petrol mixed with a variety of additives. So, solution = gasoline.
A colloid is a solution that has particles ranging between 1 and 1000 nanometers, yet are still able to remain evenly distributed throughout the solution. We know that blood is thin and isn't mixed with anything but our blood. So, colloid = blood.
