An Experiment Requires 15

An experiment requires 15.0 mL of a 0.100 M solution of HCl. If you have a 12.0 M HCl stock solution in the laboratory, how would you prepare enough 0.1 M solution to run at least 3 experiments?

A) add 0.833 mL 12 M HCl stock solution to 99.167 mL water
B) add 0.833 mL 12 M HCl stock solution to 49.167 mL water
C) add 0.833 mL 12 M HCl stock solution to 199.167 mL water
