Task: Answer the multiple-choice question.
Question: Which drug has a -1.886\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a) CCCCCc1c(C)nc(NCc2ccccc2)[nH]c1=O
b) CCOC(=O)C(NC(=O)Nc1cccc(C)n1)(OCC(F)(F)F)C(F)(F)F
c) CN(C)c1cc[n+](/C(C(=S)NCc2ccco2)=C(/[O-])c2ccc(Cl)cc2)cc1
d) CC(C)CN(C(=O)CSc1nnc(-c2ccco2)o1)c1c(N)n(Cc2ccccc2)c(=O)[nH]c1=O
Answer: c. CN(C)c1cc[n+](/C(C(=S)NCc2ccco2)=C(/[O-])c2ccc(Cl)cc2)cc1
