Answer #1

The Excavata taxon contains the unicellular eukaryotic organisms with the groove feeding habitat.

The SAR or Harosa is a clade that includes three Groups named stramenopiles, alveolates, and Rhizaria. This group contains prokaryotic cells.

The metazoa group contains the eukaryotic and multicellular animals. This group only contains the animals hence no photosynthetic activity.

The plantar group contains the multicellular eukaryotic organisms with the cellulosic cell wall and photosynthetic activity.

The answer is D.
