A. Cell structure
B. Body organization
C. Presence of flagellum
D. Reproduction
E. Phylogenetic relationships
Choose the correct answer from the options given below :
- A, B, D and E only
- A, B, C, D and E
- A, B and E only
- B, C and D only
### Related Formula
Whittaker's 5 Criteria: Cell structure, Body organization, Mode of nutrition, Reproduction, Phylogenetic relationships.
### Core Logic
R.H. Whittaker (1969) used five primary criteria: cell structure (A), body organization (B), mode of nutrition, reproduction (D), and phylogenetic relationships (E). Presence of flagellum (C) was not a primary criterion.
### Step 1: Selection
Correct criteria are A, B, D, and E. Option (1) is correct.
### Pattern Recognition
Excluding 'Presence of flagellum' leaves A, B, D, E.
### Evaluation Rubric / Model Answer
