The correct answer A.eukaryotic cells ,prokaryotic cells. This means the blood cells are eukaryotic and the bacteria are prokaryotic cells.
The red blood cell although lacks nucleus still is considered to be eukaryotic in nature. The stem cell from where the red blood cell originates has a nucleus which disappears on maturity to make space available for carrying oxygen and carbon dioxide .

Explanation:
The lac operon is called lactose operon is a cluster of genes with a promoter. The bacteria uses lactose as the source of energy by the proteins coded by genes. This is present in prokaryotes.
The regulatory gene codes for repressor protein. The repressor binds to lactose and prevent its binding to operator. In the absence of lactose repressor gets activated and binds with operator. Thus, RNA polymerase is prevented from binding the promotor. The transcription of genes inhibited. Thus correct order is b, a, d, c, e.
