Task: Answer the multiple-choice question.
Question: Which drug exhibits a 0.831\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
[a] O=C(Nc1ccc(N=Nc2ccccc2)cc1)c1ccccc1Cl
[b] COc1ccc(CNC(=O)C2CCN(S(=O)(=O)c3ccccc3)CC2)cc1
[c] O=C(c1ccc(Cl)cc1)C1CCCN(Cc2ccc3nonc3c2)C1
[d] CN1CCN(S(=O)(=O)c2ccc(-c3noc(C4CCN(S(C)(=O)=O)CC4)n3)cc2)CC1
Answer: c. O=C(c1ccc(Cl)cc1)C1CCCN(Cc2ccc3nonc3c2)C1
