Task: Answer the multiple-choice question.
Query: Which compound exhibits a 8.349\% 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) C=CCn1c(COc2cccc3ccc(C)nc23)nnc1SCC(N)=O
(b) O=C(N/N=C/c1ccc([N+](=O)[O-])o1)c1cn(-c2ccccc2)nc1-c1ccccc1
Answer: a. C=CCn1c(COc2cccc3ccc(C)nc23)nnc1SCC(N)=O
