enormously in that a single tree, depending on both its size and on climate and altitude, could produce

enormously, because a single tree, being dependent on its size, climate, and altitude, is capable of producing
enormously, because a single tree, dependent both on its size as well as on climate and altitude, could produce
A:【 could 】- The tree is able to produce in the past and not anymore. This sentence is talking about a general phenomenon,一般现在时表普遍的性质或现象，更优；in that只能表达很弱的关联性，没有because的因果关联性强；
B：The tree is not 【dependent】 on anything. The production of Berries depends on the size of the tree and climate and altitude.
Verb-ed modifier can only modify the closest noun. 过去分词只能就近修饰名词
C：The sentence fragment "depending on both its size and on climate and altitude" 分类平行结构【its size】and【climate and altitude】✔
D：【 being】 is not required -> remove the being and change 【dependent】 to depending -> the sentence is great. 【of producing】表intent用不定式；
E：【dependent】错，【as well as】删去句子结构不完整，【could】改为一般现在时。
