Solution

The correct option is D b and d
Vector is a DNA molecule used in genetic engineering as a vehicle to carry foreign genetic material from one cell into another cell where it is replicated or expressed. Examples of vectors include plasmid, cosmid, Lambda phages (bacterio phage).
So the correct answer is option D.
