Task: Answer the multiple choice question.
Query: Which drug exhibits a -0.131\% 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 additional words.
Options:
a: COc1ccc(Nc2nnc(SCC(=O)NC3CC3)s2)cc1
b: CNC(=S)N(Cc1ccc(OC)cc1)Cc1cc2cccc(C)c2[nH]c1=O
Answer: b. CNC(=S)N(Cc1ccc(OC)cc1)Cc1cc2cccc(C)c2[nH]c1=O
