Task: Answer the multiple choice question.
Query: Which drug exhibits a 8.220\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a: O=C(NCc1cccnc1)Nc1ccc(Cl)c(Cl)c1
b: CCOc1ccccc1NC(=O)c1cc(C(=O)c2cc(OC)ccc2O)coc1=N
c: COc1ccc(CNC(=O)COC(=O)CCCOc2ccc(Cl)cc2Cl)cc1
d: Cc1cccc(OCCNC(=O)c2cccc(Oc3ccc(C(F)(F)F)cc3[N+](=O)[O-])c2)c1
Answer: b. CCOc1ccccc1NC(=O)c1cc(C(=O)c2cc(OC)ccc2O)coc1=N
