Task: Answer the MCQ question.
Question: Which drug exhibits a 11.735\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a. CCCOc1ccc([N+](=O)[O-])cc1C1NC(=S)NC(c2ccccc2)=C1C(=O)OCC
b. CC1(c2ccc3c(c2)OCCCO3)NC(=O)N(CC(=O)NCCc2ccccc2)C1=O
Answer: a. CCCOc1ccc([N+](=O)[O-])cc1C1NC(=S)NC(c2ccccc2)=C1C(=O)OCC
