Task: Answer the multiple choice question.
Question: Which drug has a -20.742\% 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(/C(=N\O)n1cncn1)c1ccc(Br)cc1Br
(b) Cc1nnsc1C(=O)NNc1ccc(C(C)C)cc1
Answer: a. O=C(/C(=N\O)n1cncn1)c1ccc(Br)cc1Br
