The correct answer is that "the T cell enters a state of anergy".
The activation of T cells requires two signals: (1) antigen specific signal presented by an antigen presenting cell (either a macrophage or a dendritic cell) that activates t cell receptors and (2) co-stimulatory signals that is not antigen specific but rather found in the plasma membrane of the antigen presenting cell (i.e. CD28). In the absence of a co-stimulatory signal, the t cell will enter a state of anergy or the inability to produce an immune response toward an offending antigen.

The ability to sustain aerobic activity for a prolonged period of time is known as cardiorespiratory fitness.
Cardiorespiratory fitness or endurance refers to the ability of the circulatory as well as respiratory systems of the body to provide fuel or power during sustained aerobic activity.
In order to enhance one's cardiorespiratory fitness, physical activities which maintain heart rate elevations at a safe level for a sustained length of time, like walking, running, cycling, etc. need to be attempted.
The cardiorespiratory fitness is linked with the functioning of heart, lungs as well as blood vessels. However, one should slowly increase the pace when performing such activities.
