Task: Answer the multiple choice question.
Question: Which drug exhibits a 3.760\% 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 other words.
Options:
[a] CCCCC(=O)Nc1ccc(C(=O)OC2CCCCC2)cc1
[b] O=C1NC(=O)C2(Cc3ccccc3N3CCCC32)C(=O)N1
[c] CCC(C)(C)n1nnnc1CN1CCN(c2nc3cc(OC)ccc3cc2C#N)CC1
