Task: Answer the multiple choice question.
Query: Which drug has a 8.412\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a CN1CCN(S(=O)(=O)c2ccc(NC(=O)C(C)(C)C)cc2)CC1
b Cc1ccccc1NC(=O)Cn1nc(-c2ccc(Cl)s2)ccc1=O
c COC(=O)CCC(=O)OC1(C)C(=O)C2=CN(CCN3CCOCC3)C(c3ccc(OC)cc3)=CC2=C(Br)C1=O
Answer: a. CN1CCN(S(=O)(=O)c2ccc(NC(=O)C(C)(C)C)cc2)CC1
