Which of the following is the INCORRECT step for constructing a perpendicular to a line through a point not on it?
Step 1 : Given a line l and a point M not on it.
Step 2 : With M as centre, draw an arc which intersects line l at two points P and Q.
Step 3 : Using the same radius and with P and Q as centres, construct two arcs that intersects at a point say N on the other side.
Step 4 : Join MN. Thus MN is perpendicular to l.
A Only Step 1
B Both Step 3 and Step 4
C Only Step 3
D All steps are correct.
