Task: Answer the multiple choice question.
Question: Which drug has a 8.681\% 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: CSc1ccccc1NC(=O)CN(C)C(=O)CNc1ccc(C(F)(F)F)cc1[N+](=O)[O-]
b: COCCCNC(=O)c1ccc(CNS(=O)(=O)c2ccc(NC(C)=O)cc2)cc1
Answer: a. CSc1ccccc1NC(=O)CN(C)C(=O)CNc1ccc(C(F)(F)F)cc1[N+](=O)[O-]
