In the search for alien life, astronomers have recently begun studying a promising region, a solar system that is populated by a number of potentially life-friendly planets formed by fragments of an exploding star some 7 million years ago and features many of the geological and climatic prerequisites for the evolution of life.

A...
B. featured
C. had featured
D. featuring
E. feature

what is the correct line of reasoning for the tenses at play?
OA says: D

I remember seeign this problem recently. Will search the thread and post.

Meanwhile, here is my takeaway from Ron.

features is modifying planets. It should not be a verb but a participle modifier. So, "features" should be either present participle or past participle. But, because "the geological and climatic prerequisites " are something that are still featured by the planets, the modifier should take the form of a present participle.
