Ans : (d) spindle fibres, centrioles and cilia.
The microtubules are found in the cytoplasmic matrix of all eukaryotic cells. They also occur in cilia, flagella, centrioles, basal bodies, and mitotic apparatus.
Spindle fibers form the protein structure which helps in mitosis and meiosis.
Centrioles are the two cylindrical structures of a cell organelle called centrosome.
Cilia and flagella are fine hair-like outgrowths of the membrane.
While peroxisomes are the microbodies.
