Task: Answer the multiple-choice question.
Query: Which compound has a 21.302\% 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: O=C(Nc1cccc(O)c1)c1ccc2c(c1)C(=O)N(Cc1ccco1)C2=O
b: O=C(CN1CCN(Cc2ccccc2)CC1)Nc1ccccc1-c1ccccc1
c: CN(C)S(=O)(=O)N1CCN(C(=O)N2CCCCCC2)CC1
d: CCOc1ccc(-c2cc(N3C(=O)Nc4ccccc4N3O)on2)cc1
e: CCOc1ccc(S(=O)(=O)N(C)c2ccc(OCC(=O)NCC3CCCO3)cc2)cc1
Answer: d. CCOc1ccc(-c2cc(N3C(=O)Nc4ccccc4N3O)on2)cc1
