Sgf boss mustapha takes oath office

I think there may be a slight misunderstanding. SGF stands for Secretary to the Government of the Federation, which is a high-ranking official in the Nigerian government. Boss Mustapha is the current Secretary to the Government of the Federation.

If you're referring to Boss Mustapha taking an oath of office, I believe you may be referring to his inauguration ceremony when he was first appointed to the position. In that case, yes, Boss Mustapha did take an oath of office when he was sworn in as the Secretary to the Government of the Federation.

However, if you're referring to something else, please clarify and I'll do my best to assist you.
