Step 1 — Evaluate Statement I:
Methyl orange is indeed a weak acid (it is an azo dye that acts as a weak acid indicator). Statement I is correct ✓

Step 2 — Evaluate Statement II:
- Quinonoid form (acidic medium, red/pink): more intensely coloured due to extended conjugation
- Benzenoid form (basic medium, yellow): less intensely coloured
- The quinonoid form is MORE deeply coloured than the benzenoid form
- Statement II is incorrect ✗ (it says benzenoid is more intense, which is wrong)
