It is between A and B.
But if the species is going to be extinct, that means that they are being threatened.

The stem has more things to transport that's why it has more vascular bundles. The roots only get water from the ground and moving nutrients from the soil to transfer it to the stem. Having more vascular bundles helps the stems to transfer things to leaves and other parts of the plants.
It might be because making it a hybrid could help get nutrition and other things it needs. I don't know exactly though
