IMO : D

here there are two actions :
- forming of bricks out of mud or clay
- are laid in the wall in mud mortar

and hence we have to make that two action parallel.

Only d does that :

- to form the mud or clay into bricks
- to lay them in the wall in mud mortar

Hope this helps !!

IMO : D

Actions: lay and form , verb phrases must be parallel. "after some preliminary air drying or sun drying," is modifier for 2nd verb phrase.

A - Not prallel
B - forming the mud?
C - Not parallel and change of tense
D - Correct
E - Not prallel

I would request experts to help us understand the reasoning in little more detail.
Thanks,
