Task: Answer the multiple-choice question.
Query: Which drug exhibits a 5.438% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a.) Cc1n[nH]c(=O)c2cc3occc3n12
b.) C/C(Cn1nc([N+](=O)[O-])cc1C)=N\NC(=O)COc1c(Cl)cc(Cl)cc1Cl
c.) Cn1c2ccccc2c2nnc(SCc3ccc4nonc4c3)nc21
Answer: a. Cc1n[nH]c(=O)c2cc3occc3n12
