Option C i.e cl=ld is always true.
1. diameter always passes through centre let it be O.
drawing the given diagram and joining O with C and D we get 2 triangles OLC and OLD.
2. O is centre and C,D are points on circle so OC=OD= radius of circle.
3. OL is a common side in both the triangles
4. as it is given that they are perpendicular in the question, applying hypotenuse theorem in both sides. we get
and similarly for the other triangle we get for DL
Therefore CL=DL
