The correct answer is: South Gujarat.
Surti is a dialect of Gujarati spoken in the city of Surat and the surrounding areas in South Gujarat. It is a distinct dialect with its own grammar and vocabulary, and is not mutually intelligible with other dialects of Gujarati.
Surti is a very old dialect, and its origins are not entirely clear. Some linguists believe that it may have developed from a mixture of Gujarati and Marathi, while others believe that it may be a descendant of the ancient language of Saurashtra.
Surti is a very expressive dialect, and is often used in poetry and literature. It is also the language of the Surti community, which is a large and influential community in Gujarat.
The other options are incorrect because:
- Saurashtra is a region in Gujarat, but the Surti dialect is not primarily spoken there.
- Kutch is a region in Gujarat, but the Surti dialect is not primarily spoken there.
- North Gujarat is a region in Gujarat, but the Surti dialect is not primarily spoken there.
