Task: Answer the multiple choice question.
Question: Which drug exhibits a 16.033\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a.) COc1ccc2c(c1)[n+](=O)c(C(C)=O)c(C)n2[O-]
b.) Cc1ccccc1NC1=C/C(=N\S(=O)(=O)c2cccs2)c2ccccc2C1=O
Answer: a. COc1ccc2c(c1)[n+](=O)c(C(C)=O)c(C)n2[O-]
