Problem statement: Answer the multiple choice question.
Query: Which compound has a 16.063\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a) O=C(NCc1cccnc1)/C(=C/c1ccc(-c2cccc(Cl)c2)o1)S(=O)(=O)c1ccccc1
b) CCc1c(C(=O)Nc2ccc(C)c(C)c2)[nH]c(C)c1C(C)=O
Answer: b. CCc1c(C(=O)Nc2ccc(C)c(C)c2)[nH]c(C)c1C(C)=O
