A Plasmid Has Tet^r and LacZ Genes for Tetracycline Resistance

A plasmid has tet^r and lacZ genes for tetracycline resistance and ß-galactosidase,respectively.There is a single EcoRI site within lacZ,and a single HindIII site within tet^r.The EcoRI-HindIII cut plasmid is combined with a DNA fragment with compatible ends.Cells that contain the plasmid with the insert will be

A) tetracycline resistant and blue if grown on X-gal.
B) tetracycline sensitive and blue if grown on X-gal.
C) tetracycline resistant and white if grown on X-gal.
D) tetracycline sensitive and white if grown on X-gal.
E) X-gal resistant and blue if grown on tetracycline.
