Task: Answer the multiple choice question.
Query: Which compound has a 10.870% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
(a) O=C(C1CCCCN1S(=O)(=O)c1ccccc1[N+](=O)[O-])N1CCCC1
(b) CC1CCCN(C(=O)Cn2nnc(-c3ccc([N+](=O)[O-])cc3)n2)C1
(c) O=C(CN1CCOCC1)Nc1ccc(C2CCCCC2)cc1
(d) Cc1ccc(CN2CC(C(=O)N3CCN(S(=O)(=O)c4ccc(C)cc4C)CC3)CC2=O)cc1
(e) CC(C)c1ccc(NC(=S)N2CCCC(c3ccc(F)cc3)=N2)cc1
Answer: a. O=C(C1CCCCN1S(=O)(=O)c1ccccc1[N+](=O)[O-])N1CCCC1
