## Step 1This question is about the behavior of effector T-cells after they have cleared a foreign antigen. Effector T-cells are a type of T-cell that play a crucial role in the immune response. They are responsible for killing infected host cells, activating other immune cells, and regulating the immune response.## Step 2After an effector T-cell has cleared a foreign antigen, it undergoes a process called apoptosis. Apoptosis is a form of programmed cell death that allows cells to die in a controlled manner. This is a natural process that helps to maintain the balance of cells in the body.## Step 3The other options, such as increasing in size, remaining in the circulatory system, or remaining in lymph nodes, are not typical behaviors of effector T-cells after they have cleared a foreign antigen. These cells are designed to respond to a threat and then die off, allowing the immune system to move on to other tasks.
