Task: Answer the multiple-choice question.
Question: Which compound exhibits a 0.919\% human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
(a) O=C(O)C(Cl)Cl
(b) CCCOC(=O)CCn1c(=S)oc2ccccc21
(c) O=C(Nc1ccc(Cl)c([N+](=O)[O-])c1)C(NCCCO)c1ccccc1
(d) Nc1cccc(S(=O)(=O)Nc2ccc(Br)cc2)c1
(e) CC(=O)c1cc2c(cc1N)OCO2
Answer: c. O=C(Nc1ccc(Cl)c([N+](=O)[O-])c1)C(NCCCO)c1ccccc1
