Task: Answer the multiple-choice question.
Query: Which drug exhibits a 10.545\% 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(CN2C(=O)c3cccc4cccc(c34)C2=O)cc1
[b] Cn1c(=O)c2cn(-c3ccccc3)cc2n(C)c1=O
[c] COc1cccc(-n2ccnc2SCC(=O)Nc2cc(OC)ccc2OC)c1
[d] Cc1[nH]c2ccccc2c1C(=O)CSc1nc2ccccc2[nH]1
[e] CCOC(=O)c1cc2c(=O)[nH]ccc2nc1C
Answer: e. CCOC(=O)c1cc2c(=O)[nH]ccc2nc1C
