Task: Answer the multiple choice question.
Question: Which compound has a 4.338\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a: CC(=O)Nc1ccc(-c2cc(-c3ccc(NC(C)=O)cc3)nc(-c3ccc(NC(C)=O)cc3)n2)cc1
b: O=C(NCCc1csc(-c2ccc(Cl)cc2)n1)c1ccco1
c: Cc1cccc(C(=O)N2CCC(n3nnc4cc(F)ccc43)CC2)c1
d: CCOC(=O)CCP(=O)(O)C(O)(c1ccccc1)c1ccccc1
Answer: b. O=C(NCCc1csc(-c2ccc(Cl)cc2)n1)c1ccco1
