Task: Answer the multiple choice question.
Query: Which drug exhibits a 4.450\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a O=C(Nc1cccc(C(F)(F)F)c1)c1cccc(NS(=O)(=O)c2ccc(Br)c(C(=O)O)c2)c1
b CC(=O)Nc1ccc(S(=O)(=O)Nc2cccc(-c3nc4cc(C)ccc4o3)c2)cc1
c COc1ccccc1NC(=O)CCN1C(=O)c2ccccc2S1(=O)=O
Answer: c. COc1ccccc1NC(=O)CCN1C(=O)c2ccccc2S1(=O)=O
