Task: Answer the multiple-choice question.
Query: Which compound exhibits a -20.687% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a C/C(=N\NC(=O)c1ccc(O)cc1)c1ccc(N2CCOCC2)cc1
b CCN(CC)C(=O)Cc1cn(C)c2ccccc12
c CCC(N=c1cc(-c2ccc(OC)c(OC)c2)oc2ccc(C)cc12)C(=O)O
Answer: c. CCC(N=c1cc(-c2ccc(OC)c(OC)c2)oc2ccc(C)cc12)C(=O)O
