The question asks for the relative stability of the contributing structures labeled (I), (II), and (III), but the actual structures are not visible/provided in the prompt.

Because resonance/contributing-structure stability depends entirely on the specific structural details, I cannot rigorously derive the order from first principles without seeing structures (I), (II), and (III).

What is normally used to compare contributing structures

For resonance contributors, stability is judged using these standard rules:

1. Complete octets are favored over incomplete octets.
2. More covalent bonds generally means greater stability.
3. Minimum charge separation is favored.
4. Negative charge should reside on more electronegative atoms.
5. Positive charge should reside on less electronegative atoms.
6. Structures with proper valency and full octet dominate over those with valency violation or electron deficiency.

Limitation here

Since the structures themselves are missing, I cannot independently verify whether the order is:

• $(II) > (I) > (III)$
• $(III) > (II) > (I)$
• $(I) > (III) > (II)$
• $(I) > (II) > (III)$

Best possible conclusion from provided data

Given only the prompt and the stored correct answer, the marked answer is:

$\boxed{(I) > (II) > (III)}$

So the correct option is D.

Final Answer

Option D: $(I) > (II) > (III)$

However, this is based on the stored answer because the structural figures are absent from the question image/text.
