Task: Answer the MCQ question.
Query: Which drug exhibits a -3.387\% 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] COc1ccc(CN2CCN(S(=O)(=O)c3ccccc3)CC2)cc1Br.O=C(O)C(=O)O
[b] COc1cc(NC(=O)c2cc(-c3cccs3)on2)cc(OC)c1OC
[c] CC1(C)CC(=O)C2=C(C1)OC(N)=C(C#N)C21C(=O)N(CN2CCOCC2)c2ccccc21
Answer: b. COc1cc(NC(=O)c2cc(-c3cccs3)on2)cc(OC)c1OC
