Task: Answer the multiple choice question.
Question: Which compound has a 14.268\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a) CCC(C)(C)n1nnnc1C(c1ccc2ncccc2c1)N1CCN(c2nc3ccccc3s2)CC1
b) O=C(Nc1nc(-c2ccccn2)cs1)C1CC1
c) CCOC(=O)c1c(C)[nH]c(C(=O)OC/C(O)=C(\C#N)c2nc3ccccc3[nH]2)c1C
Answer: b. O=C(Nc1nc(-c2ccccn2)cs1)C1CC1
