d. No longer dividing cells of the mammalian brain

Explanation:

Cell cycle consists of events that lead to the duplication of DNA and division of cell into two daughter cells. It occurs in the zygote to make more cells for building an organism. It also occurs in skin, blood and other internal organs for self renewal.

It consists of G1, S, G2 and M phase. DNA replication occurs in S phase of cell which means that it is in the process of dividing. No longer dividing cells of mammalian brain have exited the cell cycle and are in resting phase which is also called as G0. They cant form new cells hence wont have DNA replication. Thus, these cells would be least likely to contain cells in S phase.
