Task: Answer the multiple-choice question.
Question: Which drug has a 8.448\% 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 CC1(C)CC(=O)N(Cc2ccccc2)C(=O)C1
b COc1cc2c3nnc(-c4ccccc4)c-3cn(Cc3ccc(F)cc3)c2cc1OC
c CCc1ccc(CC2S/C(=C(\C#N)C(C)=O)NC2=O)cc1
Answer: c. CCc1ccc(CC2S/C(=C(\C#N)C(C)=O)NC2=O)cc1
