    Given below are the steps of construction to construct a quadrilateral ABCD where AB = 5.6 cm, BC = 4.1 cm, CD = 4.4 cm, AD = 3.3 cm and\[\angle A=75{}^\circ \]. Which of the following steps is INCORRECT?
    Step 1: Draw \[\text{AB = 5}\text{.6 cm}\]and construct\[\angle BAX=75{}^\circ \].
    Step 2: With A as centre and radius = 3.3 cm, cut off AD = 3.3 cm along AX.
    Step 3: Join BD. With D as centre and radius = 4.1 cm, draw an arc.
    Step 4: With B as centre and radius \[=4.1cm\], draw an arc to cut the arc drawn in above step at C. Join BC, CD to obtain the required quadrilateral ABCD.

    A)  Step 1 only                 

    B)  Step 2 only     

    C)         Step 3 only     

    D)         Step 4 only                 

    Correct Answer: C

    Solution :

    Step III is incorrect since with D as centre CD is drawn with radius = 4.4 cm.
