Appointment of Additional Director

Dear Team,

I need a clarification with regard to matter cited below;

We have a company called "X Private Limited" having two directors and they are the only Share holders. Unfortunately 10 months before a director had passed away.

Kindly let me know whether;

i) An additional director be appointed with only 1 director on board.

ii) Section 174 (3) of Companies Act 2013 can be invoked if in a board of 2 directors 1 has passed away leaving only 1 on board

Thanks
