Your answer is D. Symmetry:)

Symmetry ( D )

Explanation:

Muslims and Persians stressed perfect symmetry in their architectural designs so that each side of a building would look exactly the same as the others this is because symmetry helps to make similar parts or faces of Architectural designs or whatever kind of design or drawing maintain its similarity and uniqueness.

The other properties of the architectural designs would vary form time to time like with angles slopes and texture of the designs would vary depending on other factors like the location of the design and purpose of the design but symmetry ensures uniqueness and this helps make the design look the same each type it is seen or reproduced.
