Answer:
C. Damaged vascular tissue could cause the fruit to not completely develop or even develop at all.
Explanation:
If the vascular tissues such as xylem and phloem are damaged, the fruit does not completely develop because the food that is produced in the leaves does not reach to the seed. The xylem helps in the transportation of water from the soil that is necessary for making of food during the process of photosynthesis so damaged xylem will not produced food and no food will be transported from leaves to seeds and if some food is produced by the leaves the phloem does not transport it to the seeds.
