Task: Answer the multiple choice question.
Query: Which compound exhibits a 6.089\% 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: CCN(CC)C(=O)C1CCN(Cc2cn(C)nc2-c2ccc(Oc3ccccc3)cc2)CC1
b: CCOc1cc(/C=C2/NC(=O)NC2=O)cc(Br)c1OCc1ccc(C(=O)O)cc1
c: CCOC(=O)CSc1nc(N)c(C#N)cc1C#N
d: COC(=O)C1=C(C)N(c2ccc(C(=O)OC)cc2)C(=O)C1
Answer: b. CCOc1cc(/C=C2/NC(=O)NC2=O)cc(Br)c1OCc1ccc(C(=O)O)cc1
