Task: Answer the multiple choice question.
Question: Which drug has a -18.100\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a. O=C(CCc1nc2ccccc2c(=O)[nH]1)N1CCN(S(=O)(=O)c2ccccc2Br)CC1
b. COc1cccc(NC(=S)N(CCc2ccc(OC)c(OC)c2)Cc2ccccn2)c1
c. COc1ccc(CNC(=S)Nc2ccc(F)c(Cl)c2)cc1OC
Answer: a. O=C(CCc1nc2ccccc2c(=O)[nH]1)N1CCN(S(=O)(=O)c2ccccc2Br)CC1
