Task: Answer the multiple-choice question.
Question: Which drug has a 8.674% 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(Nc1nc(-c2cccnc2)cs1)c1ccccc1[N+](=O)[O-]
(b) O=C(Nc1ccc(-c2noc(CCc3ccccc3)n2)cc1)c1ccco1
(c) CC(C)(C)CC(=O)Nc1nnc(SCC(=O)NC2CCCCC2)s1
(d) O=C(CSc1nnnn1C1CCCCC1)Nc1nc2c(s1)CCCC2
(e) CC12CN3CCN(CC(C3)/C1=N/NC(N)=O)C2
Answer: a. O=C(Nc1nc(-c2cccnc2)cs1)c1ccccc1[N+](=O)[O-]
