Given:
There are given the statement:
"Which of the following terms is defined as a set of all points in a plane that are a given distance from a point".
Step-by-step explanation:
According to the concept of the circle:
A circle is a closed two-dimensional figure in which the set of all the points in the plane is equidistant from a given point called the center.
So,
Since we know that:
A two-dimensional figure in which the set of all the points in a plane is equidistant from a given is called a circle.
Final answer:
Hence, the correct option is A.
