Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a 9.902\% 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 Cn1c(=O)c2c(nc(-n3ccnc3)n2Cc2ccc([N+](=O)[O-])cc2)n(C)c1=O
b NS(=O)(=O)c1ccc(NC(=O)COC(=O)COc2ccc(Br)cc2)cc1
Answer: b. NS(=O)(=O)c1ccc(NC(=O)COC(=O)COc2ccc(Br)cc2)cc1
