The correct answer is:
D

The group of organisms described is Euglenoids. They are characterized by a protein-rich pellicle instead of a cell wall, possess two flagella (one long, one short), exhibit mixotrophic nutrition (photosynthetic in light, heterotrophic in darkness), and are considered a link between plants and animals.

• Pellicle: Provides flexibility.

• Flagella: Two flagella, a short and a long one.

• Mixotrophic: Perform photosynthesis in light and act as heterotrophs in the dark.

• Connecting Link: Exhibit characteristics of both plants (photosynthesis) and animals (heterotrophy).
