Queen Sudoku (Daily Sudoku League #122)

This Sudoku type appeared earlier with the name Queens Sudoku. In fact, when I first created this Sudoku, I also called it Queens Sudoku. However, during testing, Prasanna pointed out that Queen Sudoku will be a better name as there is only one number that represents the Queen. I agreed with him and renamed this Sudoku. A similar Sudoku type appeared as God Save the Queen Sudoku where one number represents God and another number represents Queen. No two Queens can see each other and God is always next to a Queen. Anyway, this Sudoku does not contain the God to save Queen. 
I am posting this Queen Sudoku, as 122nd Sudoku in the Daily Sudoku League. Can you solve this Queen Sudoku puzzle?
