The correct option is
D 28G
In the first row, the number in the second column is the product of numbers on either side.
i.e.
3×9=27 And the alphabets are in alphabetical order.
In the second row, the number in the second column is the product of numbers on either side.
i.e. 7×3=21
And the alphabets differ by 1.
Similarly,
In the third row, the middle term will have a number that is the product of the numbers on either side. i.e.
