Quantitative and systemic data
Covalent bonds is important in four macromolecules such as proteins (polymers of amino
acids), nucleic acids (polymers of nucleotides), carbohydrates (polymers of
sugars) and lipids (with a variety of modular constituents) because they served
as a basic structure of macromolecules.
In addition, the resulting covalent bond is a result
of sharing a pair of electrons, one from each atom or molecular units.
I believe it's B and C because "Chloroplast" and "Vesicle" are found in plants not animals
