Problem statement: Answer the multiple-choice question.
Question: Which compound exhibits a 2.888\% human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a. CCOc1ccc(NC(C)c2cc(Cl)ccc2O)cc1
b. CN(CC(=O)Nc1ccc(Cl)c(C(F)(F)F)c1)C(=O)C1CCC1
c. COc1cccc(C2C(C#N)=C(N)Oc3c2oc(CO)cc3=O)c1OC
Answer: c. COc1cccc(C2C(C#N)=C(N)Oc3c2oc(CO)cc3=O)c1OC
