Task: Answer the multiple-choice question.
Query: Which drug has a 9.965\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a: CCS(=O)(=O)CCSc1nc(C)cc(C)c1C#N
b: Cc1cccc(OC(=O)c2sc(Cl)nc2C)c1
Answer: a. CCS(=O)(=O)CCSc1nc(C)cc(C)c1C#N
