Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
a CCC(C)N(C(=O)CSc1nnc(-c2ccco2)n1C)C1CCS(=O)(=O)C1
b CN(C)/C=C/C(=O)c1ccc2noc(-c3ccc(F)cc3)c2c1
c CC(C)[C@H](NC(=O)[C@@H]1Cc2c([nH]c3ccccc23)C2c3ccccc3C(=O)N21)C(=O)NCC1CCCO1
d CCO[C@@H]1OC(C(=O)O)=C[C@H](c2ccc(C(F)(F)F)cc2)[C@H]1CCCO
