Task: Answer the multiple-choice question.
Question: Which compound exhibits a 18.704% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a: Cc1csc(NC(=O)/C=C/c2ccco2)n1
b: COC(=O)c1ccc(SCC(=O)NC2CCCCC2)c([N+](=O)[O-])c1
c: COC(=O)c1sc(NC(=O)c2cnccn2)c(C(=O)OC)c1C
Answer: c. COC(=O)c1sc(NC(=O)c2cnccn2)c(C(=O)OC)c1C
