Problem statement: Answer the MCQ question.
Question: Which drug has a 15.078\% 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: CCCS(=O)(=O)c1nc(C)cc(C)c1S(C)(=O)=O
b: CCN(CC(=O)Nc1ccc(NC(C)=O)cc1)C(=O)/C=C/c1cccs1
Answer: a. CCCS(=O)(=O)c1nc(C)cc(C)c1S(C)(=O)=O
