The correct option is D codeine

Secondary metabolites are compounds, which unlike biomolecules or the primary metabolites, are not directly involved in the normal growth, development or reproduction of the organism. Secondary metabolites are usually present in cells of plants, fungi and other microbes.
Alkaloids are nitrogen containing secondary metabolites obtained from plants. These include morphine, codeine, etc. Other secondary metabolites are terpenoids (monoterpenes, diterpenes), polymeric substances (rubber, gums, cellulose), drugs (vinblastin, curcumin), etc.
