The right option is a. thick bark  

Thick bark is the adaptation that enables deciduous trees to produce more food.  

Deciduous trees are trees such as oak, maple, and hickory trees which lose their leaves for part of the year. Bark is an important part of a tree that protects the tree. The thick bark of the deciduous trees is composed of many layers and it provides the tree with the necessary nutrients and moisture it needs for its growth. The inner back layer (phloem) transports nutrients produced by photosynthesis from the leaves of the tree, and conveys it to the branches, trunk and down to the roots of the tree.
