Answer 1

Hint: Health is a condition of complete physical, mental, and social well-being that is free of disease and infirmity. Over time, a variety of definitions have been utilised for various purposes. Health can be improved by encouraging healthy behaviours, such as regular physical activity, and limiting or avoiding unhealthy behaviours, such as smoking and excessive stress. The social and economic environment, the physical environment, and a person's unique features and actions are all major determinants of health, according to the World Health Organization.

Complete explanation:
Option A: Silent mutations are DNA mutations that do not affect human health because they do not significantly alter the phenotype of the organism in which they occur. Lifestyle decisions have an impact on cardiovascular, psychological, nutritional, skeletal, and neurological health. Infection occurs when a pathogen invades and multiplies in tissue.
So, option A is incorrect.
Option B: The infection attacks the host's cells quickly, weakening the immune system and producing sickness. Silent mutations are DNA changes that have no effect on human health because the phenotype of the organism in which they arise is not appreciably altered.
So, option B is incorrect.
Option C: When a pathogen invades and multiplies in tissue, infection occurs. The pathogen rapidly damages the host's cells, compromising the immune system and causing illnesses. Cardiovascular, psychological, nutritional, skeletal, and neurological health are all affected by lifestyle choices. Excessive smoking and alcohol consumption, for example, are both linked to stroke, heart disease, and cancer. A mutated or defective gene or collection of genes causes a genetic illness. These illnesses can strike any region of the body, including the brain and muscles.
So, option C is correct.
Option D: The infection attacks the host's cells quickly, weakening the immune system and producing sickness. Stroke, heart disease, and cancer are all connected to excessive smoking and alcohol intake, for example. A genetic ailment is caused by a mutant or faulty gene or set of genes. Any part of the body, including the brain and muscles, might be affected by these ailments.
So, option d is incorrect.

Therefore, Option C is the correct answer.

Note:
A state of total physical, mental, and social well-being that is devoid of disease and infirmity is defined as health. One of the most essential variables impacting economic development in every economy is human health. The most significant and urgent repercussions of global environmental deterioration are harm to human health. There are numerous elements that can have an impact on your health. Housing, financial stability, community safety, jobs, education, and the environment are among them. These are referred to as health's broader determinants.
