Problem statement: Answer the multiple choice question.
Query: Which compound exhibits a 2.516% human ether-à-go-go related gene (hERG) inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a: O=C(CSc1ccccn1)Nc1cccc([N+](=O)[O-])c1
b: CCOC(=O)c1cc2c(ccn2-c2ccc(F)cc2)n1CC(=O)N1CCN(C(=O)c2ccco2)CC1
c: O=C(Oc1ccc(/C=N/NC(=O)c2ccccc2O)cc1)c1ccccc1
d: CC(C)(O)C#Cc1ccc(CN2CCC(n3nccc3NC(=O)C3CC3)CC2)cc1
Answer: a. O=C(CSc1ccccn1)Nc1cccc([N+](=O)[O-])c1
