Trio Sudoku (Fun With Sudoku #85)

Last week I have introduced Trio Sudoku to kids and all of them loved these Trio Sudoku variations and were asking for more puzzles. There are very few puzzles available of this type, so I promised them to make more Trio Sudoku puzzles soon. I will be creating some Trio Sudoku for experienced players too after mixing it with other Sudoku variations. Let's see how these puzzles come up. Meanwhile, I have created some  Even Odd Sudoku puzzles for kids and will introduce them to this Sudoku variation in the coming week. Let's see what will be their reaction to this Sudoku variation.  
This is my 4th Trio Sudoku puzzle, I am posting it as the 85th Sudoku in the Fun With Sudoku Series. Can you solve this Trio Sudoku puzzle?
