PD>RD Not True.

In Triangle PDQ,
If we draw the figure we find that angle QPD=60 degree. (angle R is 30 degree).
PQD=45 degree.
Therefore, DQ>PD --- (1) (side oppsite to greater angle is also greater).

IN Triangle DRQ
Similarly, angle DRQ=30 degree.
angle DQR=45 degree.
Thus, RD>DQ. ----- (2)

From (1) and (2) RD>PD... Thus (i) is sufficient to answer the question.

PD>RD is Not True.

option a
tan R= tan 30= 1/sqrt(3)= QD/RD. so, RD= sqrt(3)*QD
tan P= tan 60= sqrt(3)= QD/PD. so, PD= QD/sqrt(3)
so, PD>RD not true
so, (i) is enough to answer

(d)Both are not sufficient to answer.it is the very right answer.

both statement is not sufficient because perpendicular and base side value is not give, so unique ans cannot come with these information.
