Correct option is C
Explanation-
Centrosomes are not membrane-bound. It is composed of two centrioles and surrounding pericentriolar material. It involved in microtubule organization, especially during mitosis.
Nucleolus is not membrane-bound. It is located inside the nucleus. It is the site for rRNA synthesis and ribosome subunit assembly. It is a dense, phase-separated region, not enclosed by a membrane.
These are the two organelles that are not membrane-bound.
So, the correct answer is option c - A and C
Incorrect options-
Peroxisomes are membrane-bound. It is enclosed by a single membrane. It involved in lipid metabolism and breakdown of hydrogen peroxide.
Endosomes are also membrane-bound. It plays crucial role in sorting and transporting internalized materials (from endocytosis).
