A.
perpendicular bisector of a given straight line QR
B.
perpendicular from a given point to a given line QR
C.
perpendicular to a line from a given point P on that line
D.
given angle
Correct answer is B
QR is a given line and P is a given point. The construction is the perpendicular from a given point P to a given line QR
