Task: Answer the multiple choice question.
Query: Which drug exhibits a 12.338\% 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] COc1ccc(/C(N)=C/C(=O)C(C)(C)C)cc1
[b] CN1CCN(C2=NC3(CCCC3)C(C#N)C(=O)N2)CC1
[c] Cl.NC(CO)C(=O)NNCc1ccc(O)c(O)c1O
[d] CN1CCN(CCCNC(=O)Cn2ncc3c4ccccc4n(C)c3c2=O)CC1
[e] CN1CCN(C(c2ccccc2)c2nnnn2Cc2ccccc2)CC1
Answer: b. CN1CCN(C2=NC3(CCCC3)C(C#N)C(=O)N2)CC1
