Task: Answer the multiple-choice question.
Question: Which compound exhibits a 2.602\% 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 other words.
Options:
a CCN1CCN(CC(O)COc2ccc(C(C)=O)cc2)CC1.Cl
b Cc1ccc(S(=O)(=O)N2CCOCC2)cc1C(=O)OCC(=O)c1ccc[nH]1
c CSCCC(NC(=O)COc1ccccc1)C(=O)N1CCN(c2ccccc2F)CC1
d CCOC(=O)C1=C(C)NC2=C(C(=O)OC2)C1c1ccccc1
e O=C(CSc1nnc(SCc2cccc3ccccc23)s1)N=Nc1c(O)[nH]c2ccccc12
