Answer:
A. A set is a group or a collection of objects.
Explanation:
The correct choice is that a set is a group or a collection of objects. Each of the objects in a set are distinct and well defined.
Sets are used extensively to solve mathematical problems.
- Objects in a set are called elements.
- Different operations can be carried out on set which can give us some information about it.
- We can have set of fruits, a set of real numbers, a set of house types e.t.c.
- Sets must be properly defined.
A set is not a collect of an object but distinct objects that are well defined.
