Task: Answer the multiple choice question.
Query: Which drug exhibits a 3.878\% 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 other words.
Options:
(a) CN(C)/C=C1\SC(=S)N(c2ccc(F)cc2)C1=O
(b) O=C(COc1cccc2ccccc12)Nc1nc2ccccc2[nH]1
(c) Cc1c(Cc2ccccc2)c(=O)oc2cc(OCc3nn[nH]n3)ccc12
(d) COc1ccc(-c2cn3ccc4ccccc4c3n2)cc1
(e) C/C(=N/NC(=O)c1ccoc1C)c1ccc(N2CCOCC2)cc1
Answer: b. O=C(COc1cccc2ccccc12)Nc1nc2ccccc2[nH]1
