    2 units

    Step-by-step explanation:

    The radius of a given equation of the circle is 2 units because the general equation of a circle for two-dimension is:

    (x-a) ² + (y-b) ² = r²

    where r is the radius of a circle

    and, (a, b) is the center of a circle.

    For the given equation of a circle, we have center (7,10) and the radius is 2 units.

    Thus, the First option is correct only and not others.
