Task: Answer the multiple-choice question.
Query: Which drug exhibits a 7.649\% human ether-à-go-go related gene (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: COc1ccc2sc3ccccc3c(=O)c2c1
b: CC(C)(C)n1nc2c(c1NC(=O)c1cc(Cl)ccc1[N+](=O)[O-])CS(=O)(=O)C2
c: CC1(CCc2ccccc2)NC(=O)N(CC(=O)Nc2ccccc2C#N)C1=O
Answer: a. COc1ccc2sc3ccccc3c(=O)c2c1
