Answer 1

The correct option is C At right angles to each other due to being present in different grooves

• Whirling whips are actually the dinoflagellates having two flagella.
• These dinoflagellates are the eukaryotic algae which have two dissimilar flagella present in different surface grooves and beat at right angles.
• The movement of these flagella produces propulsion and hence aid in movement.
• The correct answer is C.
