Task: Answer the multiple choice question.
Query: Which drug exhibits a 18.040\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a. COC(=O)c1cccc(NC(=O)COc2cccc([N+](=O)[O-])c2)c1
b. COc1cccc(-c2n[nH]c(=S)n2Cc2ccco2)c1
Answer: a. COC(=O)c1cccc(NC(=O)COc2cccc([N+](=O)[O-])c2)c1
