Problem statement: Answer the multiple choice question.
Query: Which compound exhibits a -0.754\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
a CCc1ccc(OCC(=O)Nc2ncc3c(n2)CC(C)(C)CC3=O)cc1
b O=C(CCNS(=O)(=O)c1ccc(Cl)cc1)N1CCN(c2ccccn2)CC1
c COc1ccc(NS(=O)(=O)c2ccc(O)c(C(=O)OCC(=O)N3CC(C)OC(C)C3)c2)cc1
d COc1ccc(NC(=O)CC(Cc2ccccc2)C(=O)O)cc1
e COCCNC(=O)/C(C#N)=C/c1c(F)cccc1Cl
Answer: b. O=C(CCNS(=O)(=O)c1ccc(Cl)cc1)N1CCN(c2ccccn2)CC1
