Answer:
A. Water and sugars
Step-by-step explanation:
However if you have the choice all of the above that would be the answer.
The reason is because phloem sap's major component is sugar. The type of sugar depends on the species, but predominanlty, glucose is what you would find. The sugars are dissolved in water, so phloem sap is water-based. I say that it should be all of the above, because it is nutrient-rich, it has hormones, minerals, and vitamins as well, which are all dissolved in water. But again, sugar makes most of the phloem sap.
