Task: Answer the multiple choice question.
Question: Which compound has a -6.324\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
(a) c1cc2ccc3ccc(CN4CCOCC4)c4ccc(c1)c2c34
(b) C1=C(CCNc2ncnc3c2cnn3-c2ccccc2)CCCC1
(c) Cc1ccccc1S(=O)(=O)Nc1cccnc1
(d) CCN1C(=O)c2n[nH]c(C(=O)OC)c2C1=O
(e) O=C(OCC(=O)N1CCN(c2ccccc2)CC1)c1cc(Cl)ccc1[N+](=O)[O-]
Answer: e. O=C(OCC(=O)N1CCN(c2ccccc2)CC1)c1cc(Cl)ccc1[N+](=O)[O-]
