Task: Answer the multiple choice question.
Query: Which drug exhibits a 15.643\% 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. C/C(CC(=O)Nc1ccc(Br)cc1)=N\NC(=O)c1cccc(O)c1
b. CC1CC(C)CN(S(=O)(=O)c2ccc3c(c2)oc(=O)n3CC(=O)NCCCOC(C)C)C1
Answer: a. C/C(CC(=O)Nc1ccc(Br)cc1)=N\NC(=O)c1cccc(O)c1
