A.

B.
I watched a trees's branches sway in the wind.

C.
I watched a tree's branches sway in the wind.

D.
I watched a trees' branches sway in the wind.



Answer :

The answer would be D.

Hope this helps!! :)
When 2 words in a row contains "s" at the end, you put an apostrophe at the end of the first word containing "s" at the end in that specific word

In, "I watched a trees' branches sway in the wind," "trees" and "branches" are the words containing s at the end of the word in a row.

And the first word containing s at the end is "trees," so you put in an apostrophe as it is in choice D

So yes, i agree with what the other one says. It is D.
