The main difference between islamic art and both egyptian and greek art is its
a. use of people and animals to honor deity.
b. avoidance of figural imagery and use of calligraphy as an alternative.
c. interest in religion and the afterlife.
d. use of natural materials and methods of creating art.

I believe the answer is: avoidance of figural imagery and use of calligraphy as an alternative.

In Egyptian and Greek , most of its art consist some sort of figural imagery. This could be seen in many wall paintings or relief in their ancient buildings.

For islamic nations, the use of Calligraphy is more popular compared to figural imagery since depicted the God in picture is considered as a Sin for muslims.
