Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 12.938\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a. CC1(c2nnc(-c3ccccc3)o2)CC(c2ccc(F)cc2)=NO1
b. CC(=O)C1=C(c2ccccc2)NC(=O)NC1c1ccc(O)c(Cl)c1
Answer: b. CC(=O)C1=C(c2ccccc2)NC(=O)NC1c1ccc(O)c(Cl)c1
