Task: Answer the multiple choice question.
Query: Which drug has a -3.842\% 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, or d without using any additional words.
Options:
(a) COc1ccc(C2/C(=C(\O)c3ccc4c(c3)OCCO4)C(=O)C(=O)N2CCCN(C)C)c(OC)c1
(b) Cc1ccc(OCC(=O)Nc2cc(S(=O)(=O)N3CCCCC3)ccc2C)c([N+](=O)[O-])n1
(c) CC(Oc1ccccc1)C(=O)OCn1nnc2ccccc2c1=O
(d) O=[N+]([O-])CCO
Answer: a. COc1ccc(C2/C(=C(\O)c3ccc4c(c3)OCCO4)C(=O)C(=O)N2CCCN(C)C)c(OC)c1
