Task: Answer the multiple choice question.
Query: Which drug exhibits a 13.581\% 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] O=C(O)c1ccc(NC(=O)C2COc3ccccc3O2)cc1
[b] O=C1c2ccccc2NC2(CCCCC2)N1N=C1CCCCC1
[c] CC(=O)N1CCSc2ccc(S(=O)(=O)NCCc3cccc(C)c3)cc21
Answer: b. O=C1c2ccccc2NC2(CCCCC2)N1N=C1CCCCC1
