    Step I & Step V are in correct order while constructing an equilateral triangle one of whose altitudes measures 5 cm. Which of the following options is CORRECT while arranging the remaining steps in CORRECT order? Step I : Draw a line XV.
    (i) From\[\angle P,\]set off PA = 5 cm, cutting PQ at A
    (ii) From P, draw \[PQ\bot XY.\]
    (iii) Mark any point P an XY.
    Step V : Construct \[\angle PAB={{30}^{o}}\]and \[\angle PAC={{30}^{o}},\]meeting XY at B and C respectively.

    A) \[(i)\to (ii)\to (iii)\]           

    B) \[(iii)\to (ii)\to (i)\]

    C)        \[(ii)\to (i)\to (iii)\] 

    D)        \[(iii)\to (i)\to (ii)\]
