Recombinant DNA works when the host cell expresses protein from the recombinant genes.

A significant amount of recombinant protein will not be produced by the host unless expression Factors are added.

Hi, according to wiki, An expression vector, otherwise known as an expression construct, is usually a plasmid or virus designed for protein expression in cells.

The vector is used to introduce a specific gene into a target cell, and can commandeer the cell's mechanism for protein synthesis to produce the protein encoded by the gene.

Vector is not just a plasmid. There are many types of vectors. Like bacterial artificial chromosome and Yeast chromosome etc.

Why option D is not correct? As BAC and YAC are also expression vector's.

Bac and yac are advance form of cloning vectors, they are not expression vectors.

Yes, but good vectors for cloning large DNA. But expression vectors are specific for the expression for an insered gene.
