Given below are the steps of construction of a pair of tangents to a circle of radius 6 cm from a point on the concentric circle of radius 8 cm. Find which of the following steps is INCORRECT? Steps of Construction

Step I: Take a point O on the plane paper and draw a circle of radius \[OA=6\text{ }cm\]. Also, draw a concentric circle of radius\[\text{OB}=8\text{ }cm\]

Step II: Find the mid-point A of OB and draw a circle of radius BA = AO. Suppose this circle intersects the circle of radius 6 cm at P and O.

Step III: Join BP and 8Q to get the desired tangents.

A)  Step I          

B)  Step II

C)  Step I and Step II                

D)  Step II and Step III
