Given below are the steps of construction of a quadrilateral WXYZ, where WX = 7.5 cm, XY = 9 cm,

∠W = 80° , ∠X = 115° and ∠Y = 110° .

Which of the following is a wrong step?

(i) Draw WX = 7.5 cm.

(ii) Draw ∠AWX = 80° at W and ∠BXW = 115° at X.

(iii) With X as a centre and radius 9 cm, draw an arc
to intersect XY at Y.

(iv) Draw ∠XYZ = 110° such that ZY meets WA at Z.

A(iii) and (iv) only

B(iii) only

C(ii) and (iv) only

D(ii) only

Please explain how statement iv is wrong
