Task: Answer the multiple-choice question.
Question: Which drug has a 12.922\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
[a] COc1cc(C(=O)NCc2cccc3ccccc23)cc(Cl)c1OC
[b] Cc1[nH]nc2c1C(c1ccc(OC(=O)c3ccco3)cc1)C(C#N)=C(N)O2
[c] COc1ccc2c(c1)cc(C(=O)N[C@H](C(=O)N1CCC[C@H]1C(=O)O)C(C)C)n2C
[d] N#Cc1ccc(-c2ccco2)nc1SCC(=O)c1ccc(Cl)cc1
Answer: c. COc1ccc2c(c1)cc(C(=O)N[C@H](C(=O)N1CCC[C@H]1C(=O)O)C(C)C)n2C
