Task: Answer the multiple choice question.
Query: Which drug has a 5.394\% 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: COc1ccc(OC)c(NC(=O)c2cc3c(Cl)nc4ccccc4c3s2)c1
b: Br.Cn1c(CS/C(N)=N/N=C/c2ccccc2)c(Br)c(=O)n1-c1ccccc1
Answer: b. Br.Cn1c(CS/C(N)=N/N=C/c2ccccc2)c(Br)c(=O)n1-c1ccccc1
