Constraint: Even if you are not sure, you must pick either a, b, c, d, or e without using any other words.
Options:
a) CC1(C)Cc2cccc(OC(=O)NCSc3ccc(C(C)(C)C)cc3)c2O1
b) CC(=O)c1cc2c(cc1C)C(C)(C)C(C)CC2(C)C
c) CCCC1OP(=S)(Cl)OCC1CC
d) ClC1=C(Cl)C(Cl)(C2(Cl)C(Cl)=C(Cl)C(Cl)=C2Cl)C(Cl)=C1Cl
e) CCc1cc2c(cc1C=O)C(C)(C)CCC2(C)C
