Problem statement: Answer the multiple-choice question.
Question: Which compound exhibits a 10.784\% 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) O=C(CN1CCOCC1)N/N=C/C(Br)=C\c1ccccc1
(b) O=C(CP(=O)(c1ccccc1)c1ccccc1)Nc1nc2ccc(Cl)cc2s1
Answer: a. O=C(CN1CCOCC1)N/N=C/C(Br)=C\c1ccccc1
