Task: Answer the multiple-choice question.
Query: Which drug exhibits a 8.859\% human ether-à-go-go related gene (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) COc1ccc(N2CC(NS(=O)(=O)c3cccs3)CC2=O)cc1
b) COc1ccc(C(=O)CSc2ccc3nnc(-c4cccnc4)n3n2)cc1
c) Cn1cc(SCC(=O)N2CCCc3ccccc32)c2ccccc21
d) Cc1ccc(NC(=O)C2C3C=CC4(O3)C2C(=O)N(CCCN2CCCC2)C4C(=O)NC2CCCCC2)cc1Cl
e) CC(C)C[C@H](NC(=O)NC(C)C)C(=O)O
Answer: e. CC(C)C[C@H](NC(=O)NC(C)C)C(=O)O
