Task: Answer the multiple choice question.
Question: Which compound exhibits a 10.935\% 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 other words.
Options:
[a] COc1cccc(N2CCN(CC(=O)NC3=Nc4ccccc4N=C(C)C3c3ccccc3)CC2)c1
[b] C[C@H]1CN=C(N(C)C)N1CC1CCCCC1
[c] C/C(CC(=O)Nc1ccc2c(c1)OCCO2)=N\NC(=O)c1cccc(O)c1
[d] CC1CCN(CCC(=O)N/N=C/c2ccc([N+](=O)[O-])cc2)CC1
Answer: b. C[C@H]1CN=C(N(C)C)N1CC1CCCCC1
