Question

heart disease is a noncommunicable disease because
it can be spread.
it does not spread from person to person.
it is contagious.
it only affects individuals, not communities.

Explanation:

To determine why heart disease is a noncommunicable disease, we analyze the options:

• Option "it can be spread" and "it is contagious" are incorrect as noncommunicable diseases don't spread between people.
• Option "it only affects individuals, not communities" is wrong because heart disease can affect communities (e.g., high prevalence in a population).
• Noncommunicable diseases are defined as those that do not spread from person to person, so "it does not spread from person to person" is correct.

Answer:

B. it does not spread from person to person
