Task: Answer the multiple choice question.
Query: Which compound has a -9.466% human ether-à-go-go related gene (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=C1CC(N2CCN(c3ccccc3)CC2)C(=O)N1c1cccc(Br)c1
[b] [O-][N+]12CC[N+]([O-])(CC1)c1ccccc12
[c] O=C(Cn1c(NCCO)nc2ccccc21)N1CCN(Cc2ccccc2)CC1
Answer: c. O=C(Cn1c(NCCO)nc2ccccc21)N1CCN(Cc2ccccc2)CC1
