Health-related fitness components:
Health-related fitness refers to the aspects of physical fitness that are related to good health and the prevention of disease. There are five components of health-related fitness, and two of them are flexibility and muscular strength.

1. Flexibility:
Flexibility is the ability of joints to move through a full range of motion. It is an important component of health-related fitness because it helps to prevent injuries and improves overall physical performance. Flexibility exercises involve stretching muscles and tendons, which improves joint mobility and muscle elasticity. Examples of flexibility exercises include stretching exercises, yoga, and Pilates. Flexibility is important for maintaining good posture, reducing muscle tension, and increasing muscular balance.

2. Muscular strength:
Muscular strength is the ability of muscles to exert force against resistance. It is also a component of health-related fitness because it helps to improve overall physical performance and prevent injuries. Muscular strength exercises involve using resistance, such as weights or resistance bands, to challenge and strengthen the muscles. Examples of muscular strength exercises include weightlifting, push-ups, and squats. Muscular strength is important for performing daily activities, such as lifting and carrying objects, and for maintaining a healthy body composition.

Other options:
The other options listed in the question do not represent components of health-related fitness:

a) Breathing and running: While breathing is essential for exercise and overall health, it is not specifically a component of health-related fitness. Running, on the other hand, is a form of cardiovascular endurance exercise, which is another component of health-related fitness.

c) Muscular endurance and push-ups: Muscular endurance is the ability of muscles to sustain repeated contractions over a period of time. While push-ups are a specific exercise that targets muscular endurance, it is not a component of health-related fitness on its own. Muscular endurance is another component of health-related fitness, along with cardiovascular endurance.

d) Jogging and swimming: Jogging and swimming are both examples of cardiovascular endurance exercises, which is a component of health-related fitness. However, they do not represent the specific components of health-related fitness listed in the question.
