Answer:

Option B. (x - h)² + (y - k)² = r²

Explanation:

Equation of a circle which passes through a point P(x, y) and center at (0, 0) then the equation of the circle is represented by

x² + y² = r²

If center of the circle is moved from origin (0, 0) to (h, k) then we have to find the equation.

(x - h)² + (y - k)² = PQ² = r² [Distance between two points P and Q]

Therefore option B is the correct answer.
