Task: Answer the multiple choice question.
Query: Which drug exhibits a 16.960\% human ether-à-go-go related gene (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: CC(=O)Cn1c(N2CCC(Cc3ccccc3)CC2)nc2c1c(=O)[nH]c(=O)n2C
b: Cc1ccc(C)c(NC(=O)c2ccc3ccccc3n2)c1
c: C/C(N)=C(/C#N)C(=O)CSc1nnc(COc2ccccc2Cl)o1
Answer: a. CC(=O)Cn1c(N2CCC(Cc3ccccc3)CC2)nc2c1c(=O)[nH]c(=O)n2C
