Task: Answer the multiple choice question.
Question: Which drug exhibits a 8.557\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a) COc1ccc(C(=O)Oc2cc(C)[nH]c(=O)c2[N+](=O)[O-])c(OC)c1
b) CCOc1ccc(NC(=O)c2ccc(-n3cccn3)nc2)cc1
Answer: a. COc1ccc(C(=O)Oc2cc(C)[nH]c(=O)c2[N+](=O)[O-])c(OC)c1
