Problem statement: Answer the multiple-choice question.
Query: Which compound has a 8.740\% 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 other words.
Options:
[a] O=S(=O)(c1cccc(Cl)c1)N1CCCC1
[b] COCCNC(=O)/C(C#N)=C/c1ccc(OCC(=O)NC2CCCCC2)cc1
[c] Fc1ccc(-c2nnc(NC3=NCCCCC3)o2)cc1
[d] COc1ccc(CN2CCN(C(=O)c3cccc(OC)c3OC)CC2)cc1OC.O=C(O)C(=O)O
Answer: b. COCCNC(=O)/C(C#N)=C/c1ccc(OCC(=O)NC2CCCCC2)cc1
