Task: Answer the multiple choice question.
Query: Which compound has a -21.395% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a O=C(OCc1ccc(Br)cc1)c1cnc(Cl)c(Cl)c1
b O=C(NC1CCCC1)c1ccc(CSCc2ccccc2F)o1
c O=C1CN(C(=O)/C=C/c2cccc(Cl)c2)c2ccccc2N1
Answer: c. O=C1CN(C(=O)/C=C/c2cccc(Cl)c2)c2ccccc2N1
