Task: Answer the multiple choice question.
Query: Which compound exhibits a 2.667\% 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 Cc1c(NC(=O)Nc2cccc(F)c2)c(=O)n(-c2ccccc2)n1C
b COc1ccc(-c2[nH]nc(-c3ccccc3)c2-c2nc3ccccc3[nH]2)cc1
c Cc1cc(C)c(C#N)c(N2CCC(C(N)=O)CC2)n1
Answer: c. Cc1cc(C)c(C#N)c(N2CCC(C(N)=O)CC2)n1
