The correct option to fill in the blank is ins and outs.

The sentence is about the trainee wanting to know the details of the course to get a better understanding of the job prospects. The phrase "ins and outs" is the most appropriate phrase to use in this context, as it refers to the details or intricacies of something.

The other options are not as appropriate:

• Bird's eye view means a general overview of something. It would not be as accurate to use "bird's eye view" in this context, as the trainee is not interested in a general overview of the course, they are interested in the details.
• Crying need means a situation that is very urgent and needs to be addressed immediately. It would not be as accurate to use "crying need" in this context, as the trainee is not asking for help, they are simply asking for information.
• Tall talk means boasting or exaggeration. It would not be as accurate to use "tall talk" in this context, as the trainee is not trying to boast or exaggerate, they are simply trying to get information.
