Task: Answer the multiple-choice question.
Query: Which drug has a 4.611\% 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 additional words.
Options:
(a) O=C(N/C(=C/c1ccc(Br)cc1)c1nc2ccccc2[nH]1)c1ccco1
(b) COc1ccccc1C/C(N)=N/O
Answer: a. O=C(N/C(=C/c1ccc(Br)cc1)c1nc2ccccc2[nH]1)c1ccco1
