Problem statement: Answer the multiple-choice question.
Question: Which drug exhibits a 16.819\% 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] O=C(CSCc1ccc(Cl)cc1)c1ccco1
[b] CCC1C(=O)N=C(SCC(=O)NC2CCCCC2)NC1=O
[c] COc1ccccc1-c1nnc(SCC(=O)OC(C)C)o1
[d] O=S(=O)(Nc1ccc2c(c1)OCO2)c1ccc(F)c(F)c1
[e] C=CCOC(=O)C1=C[C@@H](c2cn(C(C)=O)c3ccccc23)C[C@@H](OCCCCO)O1
Answer: b. CCC1C(=O)N=C(SCC(=O)NC2CCCCC2)NC1=O
