Task: Answer the multiple choice question.
Query: Which compound has a 11.879\% 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) O=S(=O)(c1ccccc1)N1CC=C(c2ccccc2)CC1
b) Cc1ccc(NC(=O)C2CC(=O)n3c(nc4ccccc43)N2)cc1
c) Cn1c(=O)c2c(nc(Br)n2Cc2ccccc2Cl)n(C)c1=O
d) Cn1c(SCC(=O)C(C)(C)C)nnc1-c1cccnc1
Answer: c. Cn1c(=O)c2c(nc(Br)n2Cc2ccccc2Cl)n(C)c1=O
