Task: Answer the multiple choice question.
Question: Which drug exhibits a -23.734\% 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: CC(=O)Nc1ccc(S(=O)(=O)NCCC(=O)OC(C)C(=O)NC2(C#N)CCCCC2)cc1
b: CCOc1cc(C2C(C#N)=C(N)OC3CCCC(=O)C32)ccc1OCCN1CCOCC1
c: O=C(Nc1ccc(CN2CCOCC2)cc1)c1ccc2ccccc2c1
Answer: c. O=C(Nc1ccc(CN2CCOCC2)cc1)c1ccc2ccccc2c1
