Task: Answer the multiple choice question.
Query: Which compound exhibits a 5.450\% 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 O=c1cc(CCl)nc2scc(-c3ccccc3)n12
b Cc1ccc([N+](=O)[O-])cc1NC(=O)CSc1n[nH]c(N)n1
Answer: a. O=c1cc(CCl)nc2scc(-c3ccccc3)n12
