Task: Answer the multiple choice question.
Question: Which compound exhibits a 20.200\% human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
[a] O=S(=O)([O-])CCC[N+]1(CC#Cc2ccccc2)CCCCC1
[b] Cn1ccsc1=NC(=O)c1cc(S(=O)(=O)N2CCOCC2)ccc1F
Answer: a. O=S(=O)([O-])CCC[N+]1(CC#Cc2ccccc2)CCCCC1
