Problem statement: Answer the multiple choice question.
Question: Which drug has a -13.540\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
[a] CC(C)(C)c1ccc(S(=O)(=O)Nc2ccc(C(=O)N3CCCC3)cc2)cc1
[b] Cl.O=C(CCN1CCC(c2ccccc2)C1)c1cccs1
[c] COc1ccc(C(=O)NCc2ccc(S(N)(=O)=O)cc2)cc1[N+](=O)[O-]
Answer: b. Cl.O=C(CCN1CCC(c2ccccc2)C1)c1cccs1
