Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a -4.324\% 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: CCOc1ccccc1NC(=O)c1c(Br)cnn1C
b: COc1ccc(NC(=O)C(=O)NCCN2CCN(C(=O)c3cccs3)CC2)cc1
c: Clc1cccc(Cl)c1CSc1nnc(-c2sccc2-n2cccc2)o1
d: Cc1onc(-c2ccccc2)c1C(=O)OCC(=O)Nc1ccc(C#N)cc1
e: C=CCOC(=O)C1=C[C@H](c2coc3ccccc3c2=O)C[C@H](OCCCCO)O1
Answer: e. C=CCOC(=O)C1=C[C@H](c2coc3ccccc3c2=O)C[C@H](OCCCCO)O1
