Task: Answer the multiple-choice question.
Question: Which compound exhibits a -0.733\% 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.) COc1cccc(CNC(=O)c2ccc(C)c(S(=O)(=O)N3CCOCC3)c2)c1
b.) CCc1ccc2nc3c(c(C(=O)O)c2c1)CCC3
c.) COc1cc2c(cc1OC)C(NC(=O)c1ccc(C)cc1)CC2=O
d.) Cc1ccc(C(C)C)c(OCC(=O)Nc2ccc3c(c2)nc(CCN2CCCCC2)n3C)c1
e.) COc1coc(/C=C/C(=O)O)cc1=O
Answer: e. COc1coc(/C=C/C(=O)O)cc1=O
