These are paired, rod-like organelles that lie at right angles to each other. They play an important role in mitosis.

Explanation:
Centrioles are the paired, cylindrical structures that lie at right angles to each other within the centrosome. They play a key role in mitosis by organizing the spindle fibers—microtubules—that pull and separate chromosomes to opposite poles. This precise spindle arrangement ensures chromosomes are distributed correctly to the daughter cells. The nucleus, Golgi apparatus, and even the centrosome as a whole don’t describe these rod-like pairs themselves or their specific job in forming the mitotic spindle, which is why centrioles are the best match.
