Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a -12.447\% 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 additional words.
Options:
(a) O=Cc1ccc(-n2nncc2-c2ccc([N+](=O)[O-])cc2)cc1
(b) O=C(CCC(=O)N1CCOc2ccc(Cl)cc21)NCCCN1CCOCC1
(c) CCc1cc2c(N3CCN(c4nnc(CC)s4)CC3)ncnc2s1.Cl
(d) O=C(Cn1nnc2ccccc21)Nc1ccccc1[N+](=O)[O-]
(e) CN1C(=O)C(O)(CC(=O)c2ccc3c(c2)OCO3)c2ccccc21
Answer: a. O=Cc1ccc(-n2nncc2-c2ccc([N+](=O)[O-])cc2)cc1
