Task: Answer the multiple choice question.
Query: Which drug exhibits a 16.093\% 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] CCOC(=O)C1=C(C)Nc2nc(SCC)nn2C1c1ccc(OC)cc1
[b] COc1ccc(NS(=O)(=O)c2cc(NC(=O)c3ccc(=O)[nH]c3)ccc2N2CCCC2)cc1
[c] CN1CCN(CCOCCOc2c(Cl)cc(Cl)cc2Cl)CC1.O=C(O)C(=O)O
Answer: a. CCOC(=O)C1=C(C)Nc2nc(SCC)nn2C1c1ccc(OC)cc1
