Task: Answer the multiple-choice question.
Question: Which drug has a 1.896\% 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) CCc1ccc(N2CC(C(=O)N/N=C/c3ccccc3OC)CC2=O)cc1
(b) CN(C)c1nnnn1Cc1ccc(Cl)cc1Cl
(c) O=C(NCc1ccccn1)NC1CCCCC1
(d) COc1ccc(N2C(=O)CSC23C(=O)Nc2ccccc23)cc1
(e) COc1cc(/C=C/C(=O)OC(C)C(=O)c2ccccc2)cc(OC)c1OC
Answer: c. O=C(NCc1ccccn1)NC1CCCCC1
