Given below are the steps of construction of a quadrilateral ABCD, where AB = 3.5 cm, BC = 6.5 cm, \[\angle A=75{}^\circ \], \[\angle B=105{}^\circ \]and\[\angle C=120{}^\circ \]. Which of the following steps is INCORRECT?

Step 1: Draw AB= 3.5cm.

Step 2: Draw \[\angle XAB\text{ }=\text{ }75{}^\circ \] at A and \[\angle ABY=105{}^\circ \] at \[B\].

Step 3: With B as centre and radius\[BC=6.5\text{ }cm\], draw an arc to intersect BV at C.

Stap4: At C, draw \[\angle ADC\text{ }=\text{ }120{}^\circ \]such that \[CZ\] meets AX at D.

A)  Step 1 only                 

B)  Step 2 only     

C)  Step 3 only     

D)         Step 4 only
