Task: Answer the multiple choice question.
Question: Which drug exhibits a -2.036% 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 additional words.
Options:
a.) CC(=O)c1ccc(NC(=O)CSc2nc(=O)cc(N)n2-c2ccccc2)cc1
b.) Cn1c(=S)[nH]c2[nH]c(=O)cnc2c1=O
Answer: b. Cn1c(=S)[nH]c2[nH]c(=O)cnc2c1=O
