附选项：
(A) the forming of bricks out of mud or clay, and, after some preliminary air drying or sun drying, they are laid
(B) forming the mud or clay into bricks, and, after some preliminary air drying or sun drying, to lay them
(C) having bricks formed from mud or clay, and, after some preliminary air drying or sun drying, they were laid
(D) to form the mud or clay into bricks, and, after some preliminary air drying or sun drying, to lay them
(E) that bricks were formed from mud or clay, which, after some preliminary air drying or sun drying, were laid
