Solution

The correct option is A True
Given: ABC, D, E, F are mid points of AB, BC, AC respectively.
AB and DF meet at O. P and Q are mid points of OB and OC respectively.
To Prove: DPFQ is a parallelogram.
Now, In ABC
D is mid point of AB and F is mid point of AC
Hence, DFBC and DF=12BC... (1) (Mid point theorem)
In OBC
P is mid point of OB and Q is mid point of OC
Hence, PQBC and PQ=12BC... (2) (mid point theorem)
thus, from (1) and (2)
DFPQ and DF=PQ (5)
Now, In ABE
D is mid point of AB and P is mid point of OB
Thus, DPAE and DP=12AE (3) (mid point theorem)
Now, In ACE
F is mid point of AC and Q is mid point of OC
Thus, FQAE and QF=12AE (4) (mid point theorem)
thus, from (3) and (4)
DPFQ and DP=FQ (6)
Now, from (5) and (6)
DPQF is a parallelogram
