Hi!
Every fall, the oak tree in the garden sheds its leaves.
The answer isn't their, because there is only one tree.
It isn't there because there isn't used as a possessive noun.
And it isn't it's because it's means it is.
So the answer is its.
Hope this helps! :)
I think A is the best answer. You should go with A.

I would say that the way nature produces things, much like how a woman grows a baby with her own body. For example: fruit on trees, etc. I hope this helps you a bit!
