Answer

Correct option: A.
Mud in water
Saltwater is a solution of salt in water in which the particles do not settle own. Blood is a natural colloid, where particles do not settle down.
But mud in water is a suspension as particles are large and heavy enough to settle down and separate from the solution when the solution is kept undisturbed for some time.
