Answer is option "b"

Step-by-step explanation:

  • The "protista" word is composed from Greek word 'protisto' means " the very first". they are unicellular which contain a nucleus and bound to the organelles.
  • Researchers estimate that protists structure a connection between plants, creatures, and organisms as these three realms wandered from a typical protist-like progenitor, billions of years back.
  • In spite of the fact that this "protists-like" precursor is a speculative creature, we can follow a few qualities found in present day creatures and plants to these old living beings.
  • For example :- algae,plasmodium, amoeba etc.
  • Hence, the right answer is option b "Protists are all more primitive than land plants and animals".
