Best Answer Explained in Below-:

The sentence "---- you ever --- to the Sundarbans?" requires the correct combination of an auxiliary verb and a past participle to form a proper question in the present perfect tense. Among the options, "A) Have ---- gone" is the only one that fits grammatically and contextually.

1. **Choice of Auxiliary Verb**: The correct auxiliary verb for forming questions in the present perfect tense with the subject "you" is "have." The present perfect tense is used to describe actions that have relevance to the present or experiences that have occurred at some unspecified time before now.

2. **Past Participle**: The word "gone" is the past participle form of "go." To ask if someone has had the experience of visiting the Sundarbans, we need to use "gone" because it reflects an action that may have taken place at some point in the past without specifying when.

3. **Invalidity of Other Options**:
- Option B ("Have ---- go") is incorrect because "go" is not in the past participle form.
- Option C ("Shall ---- go") is grammatically incorrect for this context, as "shall" indicates future intentions, not present experience.
- Option D ("Will ----- gone") is also incorrect; "will" indicates future tense, and "gone" is improperly used as it doesn't match the structure needed here (subject "you" would need "have gone").

Thus, "Have you ever gone to the Sundarbans?" is the grammatically correct and contextually appropriate sentence, confirming that the correct answer is A) Have ---- gone.
