The correct option is D Sage
If we observed 2nd and 3rd letter of all 5 words we found that
In Sage - 2nd letter A , 3 rd latter G
In Sample 2nd letter A, 3rd latter M
In Skate 2nd letter K and 3rd latter A
In Summer 2nd letter U and 3 rd Letter M
So if we are arranged in alphabetical order as in a Dictionary
Then,
Sage−>Sample−>Skate−>Summer will come.
