Say:
On the screen, we have a few books arranged as per their size on the shelf.

Steps:
These books can also be arranged as per their thickness, as they have different numbers of pages.
Hence, the answer of question (i) is yes because the arrangement will change if we arrange them as per their thickness.
Let us look at the numbers of pages of each book and arrange them as per their thickness, from left to right.
Book D has $50$ pages, the thinnest. Then book F with $100$ pages, C with $200,$ A with $300,$ B with $400,$ and finally E with $700$ pages.
Thus, the new arrangement is DFCABE.
Hence, option A is the correct answer.
