Given below are the steps of construction of a pair of tangents to a circle of radius 6 cm which are inclined to each other at an angle of 60°. Find which of the following step is wrong?                          Steps of Construction

I. With centre O and radius = 6 cm, draw a circle.

II. Taking a point b A on the circle and draw\[\angle AOB-{{120}^{o}}\].

III. Draw a perpendicular on OA at A. Draw another perpendicular on OB at B.

IV. Let the two perpendiculars meet at C.

Thus CA and C8 are the two required tangents to the given circle which are inclined to each other at\[{{120}^{o}}\].

A)  Only Step I     

B)         Only Step II                

C)  Only Step III    

D)         Only Step IV
