The complicated design of these decorations on the entryway may be one of the most important elements of its architecture. based on the context of this sentence, which would be the best synonym for complicated? challenging—backbreaking or demanding difficult—hard to do, make, or carry out; arduous elaborate—marked by complexity, full of detail or ornate involved—marked by extreme and often unneeded complexity

The answer is: Elaborate—marked by complexity, full of detail or ornate.

Elaborate means detailed and complicated in design and planning. As a consequence, because the sentence makes reference to architecture, the best synonym for complicated is elaborate, which means the decoration is sophisticated and extravagant.

The rest of the options are incorrect because they are adjectives typically used to describe situations or tasks - not a design.
