Answer:

option A, x² = 12

Step-by-step explanation:

In this question a secant has been drawn from an external point, bisecting the circle in two parts, one is 6 and second is 2 units.

From the same point a tangent has been drawn of length = x

By theorem of secants and tangent.

x² = 6 × 2 = 12

Therefore, option A, x² = 12 is the answer.
