B Correct answer
Explanation

The objective of vaccination is to provide effective immunity. The particular immune mechanisms which need to be stimulated and the site of the immune response evoked by vaccination will differ for different organisms. Mycobacteria are found as intracellular infections within macrophages and therefore stimulating T-cells to produce macrophage-activating cytokines such as IFN-gamma is appropriate in this case.
