The correct answer is biological.

When any pathogen invades the body, it has to pass several line of defence. The first barrier is skin and mucous membrane which is a physical and chemical barrier. The second line of defence is non specific response by macrophages, neutrophills and interferon. After crossing these two barriers the third line of defence comes into action in which, the B- cells and T-cells acts specifically on the pathogen and destroys it.
