C Correct answer
Explanation

Histone synthesis is tightly coupled to DNA replication. Most histone production occurs during S phase when chromosomal DNA is being duplicated. New histones are needed immediately to package the newly synthesized DNA into nucleosomes. G0 is quiescent, G1 is pre-replication, and G2 is post-replication.
