Problem statement: Answer the multiple choice question.
Query: Which compound has a -1.877\% 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 other words.
Options:
a.) COC(=O)C(c1cc(OC)c(O)c(OC)c1)(N1CCNC(C)C1)C(F)(F)F
b.) O=C(Nc1ccc(Cl)c([N+](=O)[O-])c1)c1ccc(NCCCN2CCOCC2)c([N+](=O)[O-])c1
Answer: b. O=C(Nc1ccc(Cl)c([N+](=O)[O-])c1)c1ccc(NCCCN2CCOCC2)c([N+](=O)[O-])c1
