Problem statement: Answer the multiple choice question.
Question: Which compound has a 3.623\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a: COc1ccc(Cl)cc1C(=O)Nc1ccc(OCC(=O)N2CCOCC2)cc1
b: O=[N+]([O-])c1ccc(Cl)cc1NCCCN1CCOCC1
c: O=C(N/N=C/c1cccc([N+](=O)[O-])c1)c1cc[n+](CCO)cc1.[Cl-]
d: CCOC(=O)C1CCN(C(=O)CCn2c(=O)c3cccn3c3cccnc32)CC1
e: Cc1cc(C(=O)NNC(=O)c2ccc(NC(=O)CC#N)cc2)c(C)o1
Answer: b. O=[N+]([O-])c1ccc(Cl)cc1NCCCN1CCOCC1
