Task: Answer the multiple choice question.
Question: Which drug has a 10.140\% 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 additional words.
Options:
a. Cn1c(=O)c2[nH]c(=O)cnc2n(C)c1=S
b. COc1cccc(C(=O)CN(C(=O)c2ccc(Cl)c(Cl)c2)N2C(=O)c3ccccc3C2=O)c1
Answer: a. Cn1c(=O)c2[nH]c(=O)cnc2n(C)c1=S
