Answer:
A.apple:tree
Explanation:
Both relationships, that is grape:vine and apple:tree all deal with fruits from their respective sources.
The relationship between a vine and a grape is that a vine is the climbing plant that produces grapes while a grape is a small, round, smooth-skinned edible fruit, usually purple, red, or green, that grows in bunches on certain vines.
The apple is also sourced from a tree,specifically,the apple tree so I believe apple:tree is the most similar relationship to grape:vine than the other options.
