Task: Answer the multiple choice question.
Query: Which compound has a 0.220% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
a: O=CC1=C(N2CCOCC2)/C(=C\c2ccccc2)CC1
b: CCOCCCNC(=O)C(NC(=O)c1ccccc1O)c1ccc(Cl)cc1
c: O=C(Cn1cnc([N+](=O)[O-])c1)c1ccc(Cl)cc1
d: COCCC(=O)N1CCC(Oc2ccc(C(=O)NCCC3=CCCCC3)cc2)CC1
e: Cc1c(C)[n+](=O)c(-c2ccco2)c(C)n1[O-]
Answer: b. CCOCCCNC(=O)C(NC(=O)c1ccccc1O)c1ccc(Cl)cc1
