Task: Answer the MCQ question.
Question: Which drug has a 18.878\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a.) O=C(Nc1ccc(O)c(-c2nc3ccccc3o2)c1)C1(c2ccccc2)CCCC1
b.) CS(=O)(=O)N(CC(=O)Nc1cccc(F)c1)c1cccc([N+](=O)[O-])c1
c.) O=C(CCN1C(=O)c2ccccc2S1(=O)=O)Nc1ccc(Cl)cc1
Answer: c. O=C(CCN1C(=O)c2ccccc2S1(=O)=O)Nc1ccc(Cl)cc1
