Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a 12.007\% 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 CCOC(=O)C(C)(C)N(Cc1ccc(Cl)cc1)S(=O)(=O)c1ccc(Cl)c([N+](=O)[O-])c1
b COC(=O)[C@@H](NC(=O)Nc1ccccc1F)C(C)C
Answer: b. COC(=O)[C@@H](NC(=O)Nc1ccccc1F)C(C)C
