Task: Answer the multiple-choice question.
Question: Which compound exhibits a 6.719% human ether-à-go-go related gene (hERG) inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a: CC(C)c1cc(C(N)=O)c(NC(=O)c2cccc(COc3ccc(Br)cc3)c2)s1
b: C[C@H]1CN=C(N(C)C)N1CCc1ccccc1
Answer: b. C[C@H]1CN=C(N(C)C)N1CCc1ccccc1
