Problem statement: Answer the multiple-choice question.
Query: Which drug exhibits a 9.439\% 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] CCOC(=O)C1=C(C)NC(=O)NC1C1CC=CCC1
[b] Cl.Cn1c(O)c(C=NCCCN2CCCC2=O)c(=O)n(C)c1=O.O=C(O)C(=O)O
Answer: a. CCOC(=O)C1=C(C)NC(=O)NC1C1CC=CCC1
