Given the figure of a parallelogram:
As shown:
m∠EDA = m∠HCB
We will identify the segments that are parallel
We will check the options:
A. AC || CD
Wrong because there is an intersection at point C.
B. AE || CB
Wrong, there is no line segment AE
D. AD || CB
Correct, because m∠EDA = m∠HCB
So, the answer will be D.
