Task: Answer the multiple-choice question.
Query: Which compound exhibits a 12.305\% 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. CCOC(=O)Nc1cccc2ccccc12
b. O=C1/C(=C\c2ccc(-c3ccccc3[N+](=O)[O-])o2)C(c2ccccc2)=NN1c1ccccc1
c. CCOC(=O)N=S(N)(=O)c1ccc(Cl)cc1
d. CCOc1cccc(-c2nnc3n2N=C(c2cc(OC)ccc2OC)CS3)c1
e. Cc1ccc(C)c(NC(=O)CCC(=O)OC(C(=O)c2ccccc2)c2ccccc2)c1
Answer: b. O=C1/C(=C\c2ccc(-c3ccccc3[N+](=O)[O-])o2)C(c2ccccc2)=NN1c1ccccc1
