Task: Answer the MCQ question.
Question: Which drug has a 7.064\% 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) CCCCOC(=O)C(NC(=O)c1ccccc1)=C(C)C
b) CC(C)C(=O)N(c1ccc2oc(=O)sc2c1)S(=O)(=O)c1cccs1
Answer: a. CCCCOC(=O)C(NC(=O)c1ccccc1)=C(C)C
