(C) Let us analyze the statements:$a-$ Erythrocytes of many mammals (like humans) are enucleated at maturity. This is correct.$b-$ Sieve tube cells of vascular plants lack a nucleus at maturity. This is incorrect.$c-$ Centrioles are not membrane-bound organelles. This is incorrect.$d-$ Centrioles consist of triplets of microtubules,not pairs. This is incorrect.$e-$ The cytoskeleton is composed of microfilaments,intermediate filaments,and microtubules,which are proteinaceous. This is correct.$f-$ Chloroplasts contain $70S$ ribosomes (prokaryotic type). This is correct.$g-$ Aleuroplasts store proteins,not pigments. Chloroplasts and chromoplasts are responsible for plant color. This is incorrect.$h-$ Vacuoles occupy up to $90\%$ of the volume of plant cells,not animal cells. This is incorrect.Therefore,option $C$ contains two correct statements.
