Final answer:
The true characteristic related to chronic illness is d. Noninfectious origin. Chronic diseases have a long-term progression, in contrast to acute diseases which have a rapid onset and short duration.
Step-by-step explanation:
Regarding the characteristics of chronic illness, the true option is d. Noninfectious origin. Chronic diseases often have a long duration and progress slowly. Examples of chronic diseases include type 1 diabetes and many cardiovascular diseases; these are conditions that individuals may live with for many years. It is notable that while many noninfectious diseases are chronic, some infectious diseases such as AIDS also fall into the category of chronic diseases. Conversely, an acute disease such as influenza has a short latency period with quick onset and resolution or leads to rapid death. Chronic diseases generally do not originate from an infectious agent and are characterized by long-term management rather than quick resolution.
