Task: Answer the multiple choice question.
Question: Which drug has a 14.274\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a. O=S(=O)(c1ccccc1F)N1CCN(C(=S)NCc2ccccc2)CC1
b. O=C(CC1SC2=NCCN2C1=O)Nc1ccc(Br)cc1
c. CC1C(=O)N2CCCc3cc(S(=O)(=O)N4CCN(c5cccc(Cl)c5)CC4)cc1c32
Answer: a. O=S(=O)(c1ccccc1F)N1CCN(C(=S)NCc2ccccc2)CC1
