Some letters and digits are filled in the 3×3 grid.

What is the missing letter or digit at the bottom right of the grid?

Answer: Letter F.

For each row, if there is a matchstick in the same position of both 1st and 2nd columns, then no matchstick will be in the same position of 3rd column. If a matchstick only exists in either 1st or 2nd column (but not both), then there will be a matchstick in that position of 3rd column.
