What is the best way to: To get homemade quantum dots to glow,

Available choices:
A). you need to dilute the concentrated solution of quantum dots. Quantum dots only glow at certain concentrations, so you need to pipette small amounts to a half filled vial of water and test different amount. Once you have your different vials, expose them to an ultraviolet light to see which concentration of quantum dots glow. Congrats, you have a homemade quantum dot solution.
B). you need to dilute the concentrated solution of quantum dots. Quantum dots only glow at certain concentrations, so you need to pipette large amounts to a half filled vial of water and test only one concentration. Once you have your single vial, expose it to an ultraviolet light to see if you have managed to luckily get the right concentration to have a glowing quantum dot solution.
Answer:
A).
