Problem statement: Answer the multiple choice question.
Query: Which drug has a 1.659% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a: CCCCOC(=O)C1=C(C)NC(=O)NC1c1ccc([N+](=O)[O-])s1
b: C=CCNC(=O)/C=C/c1cccs1
Answer: a. CCCCOC(=O)C1=C(C)NC(=O)NC1c1ccc([N+](=O)[O-])s1
