please provide correct option thank you

Q5) State the correct option for the following: Which statement is TRUE for dynamic equilibrium? A) A dynamic equilibrium exists once a reversible reaction occurs. the same amount of reactant and product are formed, meaning there is no net change. B) A dynamic equilibrium exists once a forward reaction occurs. Substances transition from the reactants to products until the reaction goes to completion. C) A dynamic equilibrium exists once a backward reaction occurs. Substances transition from the products to reactants until all the product is used up. D) A dynamic equilibrium exists once a reversible reaction occurs. Substances transition between the reactants and products at equal rates, meaning there is no net change. Which statement about Ksp is TRUE? A) The solubility product constant, Ksp, is the value of the equilibrium law equation for a solubility equilibrium and does not include the concentration of the solid. Ksp varies with temperature and the nature of the ionic solid. B) The solubility product constant, Ksp, is the value of the equilibrium law equation for a solubility equilibrium which also includes the concentration of the solid. Ksp varies with temperature and the nature of the ionic solid. C) The solubility product constant, Ksp, is the value of the equilibrium law equation for a solubility equilibrium and does not include the concentration of the solid. Ksp resists changing when temperature changes. D) The solubility product constant, Ksp, is the value of the equilibrium law equation for a solubility equilibrium and does not include the concentration of the solid. Ksp is the same for all ionic solids
