Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 9.386\% 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(SCC(=O)Nc2ccccc2[N+](=O)[O-])nnc1C(F)(F)F
b: C#Cc1cccc(-n2nnc(C(=O)OC)c2-c2ccccc2)c1
Answer: a. Cn1c(SCC(=O)Nc2ccccc2[N+](=O)[O-])nnc1C(F)(F)F
