Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a CC(=O)c1ccc(N2CCN(S(=O)(=O)c3c(C)[nH]c(=O)[nH]c3=O)CC2)cc1
b COC(=O)CC[C@@H](C(=O)O)N1C(=O)c2ccccc2C1=O
c O=C(Cc1ccc([N+](=O)[O-])cc1)c1ccc(O)cc1O
d COc1cc(C(=O)NC(C)c2ccc(S(N)(=O)=O)cc2)ccc1OCC(=O)N1CCOCC1
e O=C(COC(=O)Cc1ccc(S(=O)(=O)N2CCOCC2)s1)NCc1ccc(Cl)cc1
Answer: b. COC(=O)CC[C@@H](C(=O)O)N1C(=O)c2ccccc2C1=O
