Problem statement: Answer the multiple-choice question.
Query: Which drug has a -2.207\% 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] COC(=O)C1=C(C)OC(N)=C(C#N)C1c1ccsc1
[b] c1ccc(-c2ccccc2OCCn2cncn2)cc1
[c] CC(=O)n1cc(/C=N/NC(N)=S)c2ccccc21
Answer: a. COC(=O)C1=C(C)OC(N)=C(C#N)C1c1ccsc1
