Aphids are herbivorous bugs and are considered as pests they usually feed by sucking the sap
from the phloem vessels in plants anyway
the answer is B cause the sap is a solution of amino acids and sucrose so it cant be
water cause the amino acids and the sucrose are dissolved in the water
however the sap doesn't contain fats
hope i helped u :)
