Explanation:
B cells and T cells use different biological weapons to attack the pathogen. The first secrete proteins called antibodies, which are distributed via the blood or the exposed surfaces to the environment, such as mucous. Antibodies are glycoproteins that circulate in the bloodstream looking for antigens that cause some type of damage to the body. Antibodies recognize and neutralize pathogens in a highly efficient way. Once the antibodies are produced, they remain circulating in the bloodstream for several months, which generates immunity for a long period of time to a certain antigen, in other words, they are capable of recognizing other molecules (antigens) in a very specific way and forming stable complexes with them (immune complexes). Its appearance in plasma is part of the adaptive immune response, in what is known as a specific humoral response, constituting a very effective defense against pathogens.

It cannot be A because although the arctic fox population might decrease, it would only cause an increase in its prey's population as there are less predators (arctic fox) to consume it.
Tigers also have large padded feet that enable them to silently stalk prey in the Asian jungles. Each of the paw has four claws and one specialised claw called a dewclaw which are like thumbs and are used for grasping prey and climbing. I hope this helps!!
