1. Both Statement-I and Statement-II are incorrect
2. Statement-I is incorrect but Statement-II is correct
3. Both Statement-I and Statement-II are correct
4. Statement-I is correct but Statement-II is incorrect

Correct answer: Statement-I is correct but Statement-II is incorrect

Solution

Methyl orange is indeed a weak acid, which makes Statement-I correct. However, the benzenoid form is not more intensely colored than the quinoid form; in fact, the quinoid form is typically more colored, rendering Statement-II incorrect.
