The correct answer is 'don't want'.
**Explanation:**
The sentence 'I ...... to leave yet' requires a verb that expresses the speaker's current desire or lack thereof in relation to leaving. The word 'yet' indicates that the action hasn't happened up to the present moment and implies a lack of desire.
Let's review the options:
* **want:** This option is incorrect because it doesn't fit grammatically when combined with 'to leave yet'. It would imply a desire to leave, not a reason not to leave.
* **wants:** This option is incorrect because it is used with third person singular subjects (he, she, it), not with 'I'.
* **doesn't want:** This option is incorrect because it doesn't fit grammatically when combined with the subject 'I'. It is used for the third person singular 'he', 'she', or 'it'.
* **don't want:** This option is correct as it uses correct grammar for the subject 'I' and expresses the lack of a desire to leave.
Therefore, the completed sentence is:
'I **don't want** to leave yet.'
