Task: Answer the multiple-choice question.
Query: Which compound exhibits a -1.321\% 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 additional words.
Options:
(a) Cc1cc(S(=O)(=O)Nc2c(C(=O)O)[nH]c3ccccc23)ccc1F
(b) Cc1cc(C)n(-c2nc3ccccc3nc2N2CCCCCC2)n1
(c) Cn1cc(S(=O)(=O)CC(=O)Nc2ccc3c(c2)OCCO3)c2ccccc21
(d) Cc1ccc(C(CCN)c2ccco2)cc1
(e) O=C(Nc1ccccc1-c1ccccc1)c1cnccn1
Answer: e. O=C(Nc1ccccc1-c1ccccc1)c1cnccn1
