Task: Answer the multiple choice question.
Question: Which compound has a 3.794\% 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(CCNC(=O)Cn1cnc2ccccc2c1=O)NCC1COc2ccccc2O1
b. C=CCNC(=O)/C(C#N)=C/c1ccccc1[N+](=O)[O-]
Answer: b. C=CCNC(=O)/C(C#N)=C/c1ccccc1[N+](=O)[O-]
