Read the following statements regarding living organisms . How many of the following statements are incorrect ?
(i) As we go higher from species to kingdom, the number of common characteristics goes on increasing .
(ii) Lower the taxa m more are the characteristics that the members within the taxon share.
(iii) Lower the category , greater is the difficulty of determining the relationship to other taxa at the same level.
(iv) All organisms , including those in plants and animal kingdom , have sub - species as the lowest obligate category

Options

A. One
B. Two
C. Three
D. Four

Answer

To determine how many of the given statements regarding living organisms are incorrect, we will analyze each statement one by one.

### Step 1: Analyze Statement (i)
- **Statement (i)**: "As we go higher from species to kingdom, the number of common characteristics goes on increasing."
- **Analysis**: This statement is incorrect. As we move from species (the most specific category) to kingdom (the most general category), the number of common characteristics actually decreases. Species share more characteristics with each other than with organisms in higher taxonomic categories.

### Step 2: Analyze Statement (ii)
- **Statement (ii)**: "Lower the taxa, more are the characteristics that the members within the taxon share."
- **Analysis**: This statement is correct. Lower taxonomic categories (like species and genus) have members that share more characteristics compared to higher categories.

### Step 3: Analyze Statement (iii)
- **Statement (iii)**: "Lower the category, greater is the difficulty of determining the relationship to other taxa at the same level."
- **Analysis**: This statement is incorrect. Lower categories (like species) are easier to compare and determine relationships because they share more specific characteristics. Higher categories (like kingdom) are more difficult to compare due to the broader range of characteristics.

### Step 4: Analyze Statement (iv)
- **Statement (iv)**: "All organisms, including those in plants and animal kingdom, have sub-species as the lowest obligate category."
- **Analysis**: This statement is incorrect. The lowest obligate category in taxonomy is species, not sub-species. Not all species have sub-species; this is a classification that only applies to some species.

### Conclusion
- **Summary of Findings**:
- Statement (i): Incorrect
- Statement (ii): Correct
- Statement (iii): Incorrect
- Statement (iv): Incorrect

### Total Incorrect Statements
- There are **three incorrect statements** (i, iii, and iv).

### Final Answer
The number of incorrect statements is **3**.
