Speed
Agility
Balance

Explanation:
Physical fitness refers to the ability to perform physical activities well without fatigue. In other words, being physically fit refers to a state of general wellbeing. Physical fitness can either be health-related or skill-related. The skill-related components are six in number viz: agility, power, balance, coordination, speed and reaction time.
However, only four of these skill-related parts of physical fitness are mentioned in the options of this question. They are:
- Speed: This refers to the ability to run a distance in a short time frame.
- Agility: This is the ability to move easily and quickly in different directions
- Balance: The ability to maintain an upright body position during training or physical activity
- Coordination: The ability to make physical senses of one's body (eye) cooperate with the limbs (hands and feets) during a physical activity.
Note that, Aerobic Endurance and Muscular strength are health-related components of fitness
Lymphocytes that destroy foreign cells or virus- infected cells are cytotoxic T cells.
<h3>What is cytotoxic T cell?</h3>
- A particular class of immune cell that is capable of eliminating specific types of cells, such as virus-infected cells, cancer cells, and alien cells.
- To destroy cancer cells, cytotoxic T lymphocytes can be isolated from other blood cells, cultured in a lab, and then administered to a patient.
- White blood cells and lymphocytes both fall under the category of cytotoxic T lymphocytes.
- It is also known as a killer T cell and a cytotoxic T cell.
- The helper T cell and the cytotoxic T cell are the two main subtypes of T cells.
- Helper T cells, as their names imply, "assist" other immune system cells, whereas cytotoxic T cells "kill" virally-infected cells and tumours.
- The TCR cannot directly bind antigen, unlike an antibody.
