Answer:
<em>The correct option is C) It does not depend on insect pollination.</em>
Explanation:
Angiosperms can simply be described as the plants which produce flowers whereas gymnosperms are the plants which do not produce flowers. 
Both, the gymnosperms and the angiosperms, are capable of producing seeds. However, the seeds of the angiosperms are enclosed in an ovary. The seeds of gymnosperms are not enclosed.
 
<u><em>One of the major differences between gymnosperms and angiosperms is that the angiosperms have to depend on animals for pollination. On the other hand, the seeds of gymnosperms are spread through the wind and are pollinated.</em></u>
