Answer is D. hijacking of host cell's metabolic action.
In lytic cycle, phages multiplies inside the host bacterium by using the protein synthesis machinery of the bacterium and new viral particles comes out by lysing or by rupturing the host bacterial cell wall. Examples are T phages, T2, T4, T6 etc.
In lysogenic cycle, the phages does not undergo multiplication or induce breakdown of bacterium. In this the viral DNA gets integrated into the bacterial DNA without causing lysis and uses protein synthesis machinery ofthe bacterium to make viral protein. For example Lambda phages. Therefore, in both lytic and lysogenic cycle, virus uses host metabolism.
