Task: Answer the multiple-choice question.
Query: Which drug has a 12.202\% 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 or b without using any additional words.
Options:
a CN1C(=O)/C(=C2\SC(N)=NC2=O)c2ccccc21
b CC(=O)Nc1ccc(-n2nnnc2SCC(=O)N2CCN(C(=O)c3ccco3)CC2)cc1
Answer: a. CN1C(=O)/C(=C2\SC(N)=NC2=O)c2ccccc21
