Problem statement: Answer the multiple choice question.
Query: Which compound has a 2.196\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a.) CC(=O)Nc1c(C(=O)N2CCCCCC2)cnn1-c1ccccc1Cl
b.) NC1=NC[C@H](Cc2ccc(O)cc2)N1CCc1cccc(F)c1
Answer: b. NC1=NC[C@H](Cc2ccc(O)cc2)N1CCc1cccc(F)c1
