  1. Multicellularity

  2. Presence of eukaryotic cells without walls

  3. Obtaining nutrients by ingestion

  4. Storage of carbohydrates as starch

Show answer
Correct Option: D
Explanation:

Animals show different types of body organization. They are multicellular.
Animals can be Asymmetric, Radial and Bilateral symmetric.  Most of the animals are triploblastic. They obtain nutrients by ingestion, so they have a heterotrophic mode of nutrition. They store glycogen as the reserve food material.
Hence, the correct answer is 'Storage of carbohydrate as starch'.
