According to most scientists, green algae are the ancestors of plants. which statement best supports that belief?
a. both have cell walls made of cellulose, store food material as starch, and have chlorophyll a and chlorophyll b.
b. both are multicellular and haploid, are often found in fossil remains, and have cell walls made of cellulose.
c. both have cell walls made of cellulose, have xanthophyll as their chief photosynthetic pigment, and are multicellular.

The correct answer is statement A.

Explanation:

Green algae belong to the division Chlorophyta and comprise about 9000 to 12000 species. Like higher plants, green algae possess photosynthetic pigments like carotene, chlorophyll a and b, and xanthophyll, in a similar proportion as found in higher plants.  

A cell of green algae can be sessile or motile, and exhibits a central vacuole, and possesses a two-layered cell wall formed of cellulose and pectin. The storage of food takes place in the form of starch in the pyrenoids. Thus, due to the similarities in the features between the plants and green algae, it is considered that the embryophytes or the lands plants have emerged from green algae. Hence, statement A supports the belief.  

it is prolly d and c and f
