Answer:
The correct option is A. FLED is definitely a parallelogram .
Explanation:
From the given figure it is clear that the angle F and angle E are same. Angle L and angle D are same.
According to the properties of parallelogram, a quadrilateral is called parallelogram if and only if there are two pairs of congruent opposite angles (but not equal to 90°, otherwise it will be a square or rectangle).
Since we have two pairs of congruent opposite angles which are not a right angle, therefore the statement "FLED is definitely a parallelogram" is true.
Hence, option A is correct.
