Task: Answer the multiple choice question.
Question: Which compound exhibits a -12.878\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a. CC1=C(C(=O)Nc2ccc(F)cc2)C(c2ccncc2)C2=C(CCCC2=O)N1
b. NC(=O)c1ccc(NC(=O)COC(=O)CCCN2C(=O)c3cccc4cccc(c34)C2=O)cc1
c. CC1CCCN(C(=O)c2sc3cc([N+](=O)[O-])ccc3c2Cl)C1
d. CC(=O)c1ccc(NC(=O)C(C)n2c3ccccc3c3nc(=O)cc(C)n32)cc1
Answer: a. CC1=C(C(=O)Nc2ccc(F)cc2)C(c2ccncc2)C2=C(CCCC2=O)N1
