good night or good morning or good evening what ever it is im going to go to bed and wanted to say good night and hope u have a good time where ever u are

This would grammatically incorrect. You need more capitalization, punctuation, and such. It's obviously a run-on sentence as well. For it to be correct or 'proper' it would need to be as follows,

Good night, good morning, or good evening. Whatever it may be, I'm going to bed and wanted to say good night. I hope you have a good time wherever you are.

For 'legal reasons,' this entire response is a joke, haha. Sleep well jjones3161!

a, b, and c are all correct.

you need to write a question based on a prompt. you have not given the prompt, and therefore this question cannot be answered on unless you provide it.
