Solution
The correct option is D Chlamydomonas
Chlamydomonas is a microscopic, unicellular genus of green plants (algae) which live in fresh water. It consists of two filaments of cytoplasmic flagellae which project from the anterior or the apical end of the cell. The region of cytoplasm near the origin of the flagella is sensitive to light and there is a red pigment spot associated with it. When the red pigment spot's shadow is cast on the sensitive area it is thought to cause turning movements of the Chlamydomonas which brings it into the region where the intensity of the light is most suitable for it.
