Read the following statements and select the correct option w.r.t cell theory.
(i) All living organisms are composed of cells and products of cells.
(ii) Viruses are exception to cell theory because they are cellular particles.
(iii) All cells arise from pre-existing cells.
(iv) Activities of an organisms are the outcome of sum total of activities and interactions of its constituent cells.
(v) Rudolf Virchow gave final shape to cell theory.

Options

A. All expect (ii)
B. All expect (ii) & (iii)
C. All expect (iii) & (v)
D. All expect (i) & (iv)

Answer

To solve the question regarding the statements related to cell theory, we will analyze each statement one by one.

### Step-by-Step Solution:

1. **Statement (i): All living organisms are composed of cells and products of cells.**
- This statement is **correct**. The cell theory states that all living organisms are made up of cells, which are the basic structural and functional units of life.

2. **Statement (ii): Viruses are exceptions to cell theory because they are cellular particles.**
- This statement is **incorrect**. Viruses are not considered cellular; they are acellular and do not have a cellular structure. They do not fit into the cell theory as they lack cellular machinery and cannot carry out metabolic processes independently.

3. **Statement (iii): All cells arise from pre-existing cells.**
- This statement is **correct**. This principle was established by Rudolf Virchow, summarized in the Latin phrase "Omnis cellula e cellula," meaning that all cells come from existing cells.

4. **Statement (iv): Activities of an organism are the outcome of the sum total of activities and interactions of its constituent cells.**
- This statement is **correct**. The functions and activities of an organism are indeed the result of the collective activities of its cells.

5. **Statement (v): Rudolf Virchow gave the final shape to cell theory.**
- This statement is **correct**. While the initial cell theory was proposed by Schleiden and Schwann, Virchow contributed significantly by stating that all cells arise from pre-existing cells.

### Conclusion:
Based on the analysis, the only incorrect statement is the second one regarding viruses. Therefore, the correct option with respect to cell theory is that all statements are correct except for the second statement.

### Final Answer:
The correct option is: All statements are correct except for statement (ii).
