Explanation:
This is because,
Chlorine atoms (Cl2) displaces with Bromine atoms (Br) in Sodium bromide (2NaBr) solution to give a result as, Sodium Chloride (2NaCl) and left out atom Bromine (Br)

Answer: C. Suspension
Explanation: Suspensions are mixtures where its solute particles are not fully dissolved in a solvent. The size of its particles are much relatively the biggest among other mixtures such as solutions and colloids. Since its has bigger particle size it suspends and settle at the bottom of the container due to gravity. So when using suspensions it is advised to shake it well before using to mix the suspended particles.
