Task: Answer the multiple choice question.
Question: Which drug exhibits a 2.783\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a: Cc1ccccc1/C=N/NC(=O)CSc1nc2ccccc2o1
b: COc1ccc(N2C(S)=C(C#N)C(=O)NC23CCCCC3)cc1
c: CCOc1ccc(NS(=O)(=O)N(C)C)cc1
d: COC(=O)C1=C(C(=O)OC)[C@@H]2N(C)c3ccccc3[C@@]23C[C@@H](C(=O)OC)N(C(=O)c2cccs2)C3=N1
e: COc1cc(Nc2ccc(-c3ccccc3C)nn2)cc(OC)c1OC
Answer: e. COc1cc(Nc2ccc(-c3ccccc3C)nn2)cc(OC)c1OC
