Task: Answer the multiple choice question.
Query: Which drug exhibits a 7.394\% 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] COc1cccc(-c2nc(C(N)=O)c3[nH]c(=O)n(-c4ccccc4)c3n2)c1OC
[b] Cn1c(=O)c2[nH]cnc2n(C)c1=O
Answer: a. COc1cccc(-c2nc(C(N)=O)c3[nH]c(=O)n(-c4ccccc4)c3n2)c1OC
