Answer:
$AD\parallel BC$ and
$CD\parallel BA$

Explanation:

Here, Given figure is triangular prism.

And, a triangular prism consists of three rectangular shaped faces and two triangular faces.

Here, ABCD is a rectangle,

And, in a rectangle opposite sides must be parallel,

Therefore,
$CD\parallel BA$

And,
$AD\parallel BC$

But, AD and AE are not parallel because they are adjacent sides of triangle AED.

Also, DE and BA also can not be parallel to each other.

Thus, Only option first and fourth are correct.
