Centrioles are present in (1) animal cells and (2) the basal region of cilia and flagella in animals and lower plants (e.g. Chlamydomonas). In cilia and flagella, centrioles are called 'basal bodies' but the two can be considered inter-convertible. Centrioles are absent from the cells of higher plants.

This option is incorrect.

The rough endoplasmic reticulum (RER) is a cellular organelle responsible for protein synthesis

Microtubules are polymers of tubulin that form part of the cytoskeleton and provide structure and shape to eukaryotic cells. Microtubules can be as long as 50 micrometres, as wide as 23 to 27 nm and have an inner diameter between 11 and 15 nm.

Ribosomes are essential cellular structures responsible for protein synthesis, translating the genetic code from messenger RNA (mRNA) into amino acid sequences. They are found in all living cells, both prokaryotic and eukaryotic, and consist of two subunits, the small and large subunits
