    Arrange the given steps in CORRECT order, while constructing \[\Delta \,PQR\]where \[PM\bot QS\]and it is given that \[QR=4.2\text{ }cm,\]\[\angle Q={{120}^{o}}\] and \[PQ=3.5\text{ }cm.\]
    Step 1. Now, extend RQ to S and with P as centre and with a sufficient radius, draw an arc, cutting SO at A and 8.          
    Step 2. Along QX, set off \[QP=3.5\text{ }cm.\]
    Step 3. Draw a line segment \[QR=4.2\text{ }cm\]and construct\[\angle RQX={{120}^{o}}\].
    Step 4. Joint PR.
    Step 5. Joint PC, meeting RQ product at
    M. Then. \[PM\bot QS\]
    Step 6. With A as centre and radius more than half AB, draw an arc. Now with B as centre and with the same radius draw another arc, cutting the previous arc at C.

    A)  1\[\to \]2\[\to \]3\[\to \]4\[\to \]5\[\to \]6

    B)  4\[\to \]1\[\to \]2\[\to \]3\[\to \]5\[\to \]6          

    C)  2\[\to \]4\[\to \]3\[\to \]1\[\to \]5\[\to \]6          

    D)  3\[\to \]2\[\to \]4\[\to \]1\[\to \]6\[\to \]5          

    Correct Answer: D
