Problem statement: Answer the multiple-choice question.
Question: Which drug exhibits a 15.589\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a) C=CCSc1nnc(NC(=O)c2cccc(S(=O)(=O)N(C)c3ccccc3)c2)s1
b) CC1=C(C(=O)OCc2ccccc2)C(c2ccc([N+](=O)[O-])cc2)NC(=O)N1
c) O=C(NCCOc1ccccc1F)Nc1ccc(Br)cc1
d) CCCn1nnc(NC(=O)/C=C/c2ccco2)n1
Answer: c. O=C(NCCOc1ccccc1F)Nc1ccc(Br)cc1
