Problem statement: Answer the multiple choice question.
Query: Which drug has a 12.835\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
[a] COc1ccccc1/C=C/c1nc(C#N)c(N(C)C)o1
[b] COc1ccc(NC(=O)C2CCC(=O)N2)cc1
[c] O=C(Nc1ncc(Cc2cccc(Cl)c2)s1)c1ccc([N+](=O)[O-])cc1
Answer: a. COc1ccccc1/C=C/c1nc(C#N)c(N(C)C)o1
