Task: Answer the multiple choice question.
Query: Which compound has a 3.356\% 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) CCc1nc(SCC(=O)N2CCCCCC2)c2c(=O)n(C)c(=O)n(C)c2n1
(b) COc1ccc(NC(=S)N2CCN(Cc3ccco3)CC2)c(OC)c1
(c) CC(C)=CCCC(C)CN1CCC(N2CCC(C(=O)N3CCOCC3)CC2)CC1
(d) O=CN1CCN(C(=O)c2ccc(-c3nc4ccccc4s3)s2)CC1
(e) Cc1cccc(OCCCC(=O)Nc2ccc(Cl)c(S(=O)(=O)N3CCOCC3)c2)c1
Answer: d. O=CN1CCN(C(=O)c2ccc(-c3nc4ccccc4s3)s2)CC1
