Task: Answer the multiple choice question.
Query: Which compound has a 12.758\% 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) O=C(CSc1nc2ccccc2c2c1CCCC2)N1CCOCC1
b) CCc1ccc2[nH]c(=O)c(CN(Cc3ccc4c(c3)OCO4)Cc3nnnn3C3CCCC3)cc2c1
c) COc1ccc(CCNC(=O)c2c(O)c3c([nH]c2=O)CCCC3)cc1
d) CC1(C)CC(=O)C2=C(C1)NC(=O)NC2c1ccc([N+](=O)[O-])cc1
Answer: d. CC1(C)CC(=O)C2=C(C1)NC(=O)NC2c1ccc([N+](=O)[O-])cc1
