Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a.) CCCc1cc(=O)[nH]c(SCc2nc3ccc([N+](=O)[O-])cc3[nH]2)n1
b.) CC1c2[nH]c3ccccc3c2C[C@H]2C(=O)N(CCCN(C)C)CC(=O)N12
c.) Cc1ccccc1N1CCN(C2CCCN(C(=O)CCn3cnnn3)C2)CC1
d.) O=C(Cc1csc(-c2ccccc2)n1)NCc1cccs1
e.) CN(CCS(=O)(=O)c1ccc(Cl)cc1)Cc1cccnc1
Answer: a. CCCc1cc(=O)[nH]c(SCc2nc3ccc([N+](=O)[O-])cc3[nH]2)n1
