Task: Answer the multiple-choice question.
Question: Which drug has a 12.814\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a: Cn1c(NC2CCCCC2)c(N=O)c(=O)n(C)c1=O
b: C=C(C)C(=O)Nc1cccc(C2=NOC3(C2)C[C@@H](C(N)=O)N(C(=O)CC(c2ccccc2)c2ccccc2)C3)c1
c: Cc1cc(C)c(C(CC(=O)c2cccs2)C(C#N)C#N)c(C)c1
Answer: a. Cn1c(NC2CCCCC2)c(N=O)c(=O)n(C)c1=O
