Correct Answer: have worked
Solution : The second option is the correct choice.
- Here, have been working is wrongly used because we know that present perfect continuous tense is used when we talk about an action that began in the past and continues in the present . And may also continue in the future .
- The given sentence is not continuous. And the action is no longer being performed.
- Hence, the correct tense to be used here is the present perfect tense ( have worked ).
Therefore, the correct answer is: "I have worked with children before, so I know what to expect."
