Problem statement: Answer the multiple-choice question.
Question: Which compound has a 7.381\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a: C=CCN(Cc1ccc(OC)c(OC)c1)C(=O)c1cc2cc(F)ccc2[nH]1
b: CC(C)(C)c1cc(N)n2nc(C(C)(C)C)cc2n1
c: O=C1CC(c2ccccc2)CC(O)=C1C=NC1CCCC1
d: CCOC(=O)/C(C#N)=C/c1c(N2CCN(c3ccc(OC)cc3)CC2)nc2c(C)cccn2c1=O
Answer: b. CC(C)(C)c1cc(N)n2nc(C(C)(C)C)cc2n1
