You would definitely score the lowest for this particular question if you go for a similar style and material in your paper.

Here are the additions you can make to it:

1) Improve the writing style. Especially the grammer.
2) Quote other historians. I am sure they must have written a great deal about the art and architecture of the Pre-Mughal era. Infact i do have some pieces of works on this particular subject.
3) make it sound as if you are interested in informing the examiner about the particular topic. Right now you seem sooo DULL!!!!

Try to concentrate on a few examples in particular. i mean there must be a specific piece of architecture or art and write a detailed note about it. Explaining its style, its material, the design etc etc.
