Problem statement: Answer the MCQ question.
Query: Which drug has a 21.091% human ether-à-go-go related gene (hERG) inhibition at 10uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a: CCCc1c(C)nn(C(=O)/C(C#N)=N/Nc2ccccc2[N+](=O)[O-])c1C
b: Cc1ccc(-n2c(SCC(=O)OC(C)C)nnc2-c2ccccn2)cc1
Answer: a. CCCc1c(C)nn(C(=O)/C(C#N)=N/Nc2ccccc2[N+](=O)[O-])c1C
