Task: Answer the multiple choice question.
Query: Which compound has a 6.256\% 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] C#CCO[C@@H]1C[C@H](n2cnc3c(NC(=O)c4ccccc4)ncnc32)O[C@@H]1CO
[b] O=C(NN1C(=O)NC2(CCCCC2)C1=O)c1ccc(-c2ccccc2Cl)o1
[c] CCOc1ccc(-c2nnn(CC(=O)NCc3cccs3)n2)cc1
[d] COc1ccccc1C1C(C(N)=O)=C(C)Nc2nc(-c3ccccc3Cl)nn21
Answer: d. COc1ccccc1C1C(C(N)=O)=C(C)Nc2nc(-c3ccccc3Cl)nn21
