Task: Answer the multiple choice question.
Query: Which compound exhibits a 7.891\% 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) CC(=O)Oc1ccc2c(=O)c(Oc3ccccc3[N+](=O)[O-])coc2c1
(b) COc1cc(/C=C2/C(=O)ON=C2c2ccccc2)ccc1O
(c) Cc1cc(C)c2c(N)c(C(=O)NC3CC3)sc2n1
(d) Cc1ccc(/C=N/NC(=O)C(C)Oc2ccccc2[N+](=O)[O-])s1
(e) C/C(=N\NC(=O)CSc1nc2nc(C)cc(C)n2n1)c1ccccc1
Answer: b. COc1cc(/C=C2/C(=O)ON=C2c2ccccc2)ccc1O
