Hello!
"El árbol es ______", translates to "This tree is ______." Since we are given two choice, suyo and suya, one of the them is obviously feminine and ther other is masculine.
Since "el árbol" is masculine, we use the possessive word, "suyo", meaning "yours".
Therefore, el árbol es suyo.
The answer would be vende, meaning sells
Huh not a complete sentence for having wat
