Task: Answer the multiple choice question.
Query: Which drug exhibits a 6.306\% 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) COc1ccc(-c2ncncc2-c2ccccc2)c(O)c1
b) Cn1c(O)c(C(C#N)=C2N=c3ccccc3=N2)c2ccccc21
Answer: a. COc1ccc(-c2ncncc2-c2ccccc2)c(O)c1
