Task: Answer the multiple choice question.
Question: Which compound has a -0.313\% 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(CCn1c2c(c3ccccc31)CCCC2)NNC(=O)c1ccccc1[N+](=O)[O-]
b. CNC(=S)N1N=C(c2ccc(C)cc2)CC1c1ccc(Br)cc1
Answer: a. O=C(CCn1c2c(c3ccccc31)CCCC2)NNC(=O)c1ccccc1[N+](=O)[O-]
