Nerve cells do not divide because they do not have
a)	Nucleus	b)	Centrosome	c)	Golgi body	d)	Mitochondria

(b)

Centrosome or cell centre is situated close of the nuclear envelope and also called microtubule organising centre (MIOC). It plays an important role in animal cell division by producing microtubules or bipolar mitotic spindles. As the nerve cells lack centrosome, they are not capable to divide.
