Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a: CCc1ccc(C(C(=O)NC2CCCC2)N(C(=O)/C=C/C(=O)Nc2cc(C)on2)c2ccccc2C)cc1
b: Cc1ccc(S(=O)(=O)/N=C2/NC(=O)/C(=C\c3cc(Br)cc(Br)c3O)S2)cc1
c: O=C(Cc1ccccc1[N+](=O)[O-])NCCC1=CCCCC1
Answer: c. O=C(Cc1ccccc1[N+](=O)[O-])NCCC1=CCCCC1
