Task: Answer the multiple choice question.
Query: Which compound has a 19.134\% 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(=S)[nH]c2cc(-c3ccccc3)sc2c1=O
[b] CC(=O)Nc1ccc(SC[C@H](Cc2ccccc2)N2CC[C@@H](C)CCC2=O)cc1
Answer: a. C=CCn1c(=S)[nH]c2cc(-c3ccccc3)sc2c1=O
