A) inducible; the glycopeptide
B) inducible; one or more molecules used in the production of the glycopeptide

E) repressible; no molecules

Repressible operons are typically involved in anabolic pathways, such as the synthesis of a glycopeptide. The end product (in this case, the glycopeptide) often serves as a corepressor, binding to the repressor protein and enabling it to bind to the operator, thus turning off the operon.
