Question

context
our world is made up of so many entities or separate things that exist around us —its hard to keep track of them all! some scientists think there are over eight million living entities or different forms of life, such as plants, animals, and bacteria, in our world today. and that number doesnt include the non - living entities or other physical objects that are part of our reality, such as rocks or mountains. everything, from the coelacanth fish—a very rare entity that is still here from dinosaur times—to the volcano called mount vesuvius in italy, is something that impacts our world in its own way. my goal is to be an entity or being that makes our world better.
quiz what is an example of an entity?
a. an idea for a school you may build someday.
b. all the schools in an area.
c. an existing school.

Explanation:

From the context, an entity is a separate thing that exists (living or non - living). An existing school is a real, existing thing. Option a is just an idea (not an existing thing), and option b is a group of schools (not a single separate existing thing). So an existing school is an example of an entity.

Answer:

c. An existing school.
