Explanation:

- Since 2009, there (is) no cyclone there.

- The sentence uses the present tense "is," which is not appropriate for discussing events from the past up to the present.

- Option 1: are

- "Are" is the present plural form. It's unsuitable here because we're discussing the absence of cyclones from the past to now, not their current existence.

- Option 2: has been

- "Has been" correctly uses the present perfect tense, indicating a situation that started in the past and continues into the present.

- This is the correct answer.

- Option 3: were been

- "Were been" is not a grammatically correct construction in English.

- Option 4: no improvement

- Suggesting no change implies the original sentence is correct, but it's not because the tense is inappropriate.
