Answer:
The correct answer is D. A characteristic of Islamic tughras is that artists use complex arabesques and interlaced lines.
Explanation:
A tughra is a calligraphic seal for the Ottoman sultan that accompanied all official documents and correspondence. It was also used as the kingdom's emblem and stamped on the kingdom's coins.
The tughra was designed specifically at the beginning of each sultan's reign for the officially appointed court calligraph. The tughras have a characteristic, easily recognizable shape, with two loops on the left, three vertical lines in the middle, overlapping letters at the bottom and two extended lines to the right. Each of these elements has a special meaning.
