Task: Answer the multiple choice question.
Query: Which drug has a 18.978\% 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=S(=O)(/N=C/N1CCOCC1)c1ccc(Cl)cc1
(b) CN(C)C=O.O=C(Nc1cccc(S(=O)(=O)NC2=NCCCCC2)c1)c1cc(-c2ccco2)nc2ccccc12
Answer: b. CN(C)C=O.O=C(Nc1cccc(S(=O)(=O)NC2=NCCCCC2)c1)c1cc(-c2ccco2)nc2ccccc12
