Option 2nd is correct

(x-4)^2+(y-5)^2=4

Step-by-step explanation:

The equation of circle with center (h, k) and radius r units is given by:

(x-h)^2+(y-k)^2=r^2 .....[1]

As per the statement:

A circle is show in the figure with a radius of 2 units.

r = 2 units

You can see the figure, the center of the circle is given as:

Center = (4, 5)

⇒h = 4 and k = 5

Substitute the given values in [1] we have;

(x-4)^2+(y-5)^2=2^2

⇒ (x-4)^2+(y-5)^2=4

Therefore, the equation represents a circle with the same center as the circle shown but with a radius of 2 units is, (x-4)^2+(y-5)^2=4
