Task: Answer the multiple choice question.
Question: Which drug exhibits a 12.745\% 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=C(Nc1ccccc1)c1ccccc1N=Cc1cccc(O)c1
(b) CN(C(=O)COC(=O)c1cc(S(=O)(=O)N2CCOCC2)ccc1F)C1CCS(=O)(=O)C1
Answer: a. O=C(Nc1ccccc1)c1ccccc1N=Cc1cccc(O)c1
