Solution :-

Right answer is  (A)  2 units

Given that,

the circumference and the area of the circle are equal.

Let the radius (to be found) of the circle be r

Thus,

Circumference of circle = 2πr and

Area of circle = πr2

According to given condition,

2πr = πr2

2= r

Therefore, the radius of the circle is 2 units.

Hence, the correct answer is A.
