Which of the following contains a human's hereditary information?

Plasmids are small, circular DNA molecules found in bacteria and some eukaryotic cells that replicate independently of chromosomal DNA. While they can carry genes and sometimes confer traits such as antibiotic resistance, they do not contain the complete hereditary information of humans, which is encoded in chromosomal DNA.

Histones are proteins that package and order DNA into structural units called nucleosomes, playing a crucial role in the formation of chromatin. However, histones themselves do not contain hereditary information; they serve primarily as structural components that help regulate the accessibility of DNA for transcription and replication.

Adenosine triphosphate (ATP) is the primary energy carrier in cells, allowing for the transfer and storage of energy necessary for various biological processes. ATP does not contain any genetic information or hereditary data; rather, it functions in energy metabolism and is not involved in the storage or transmission of genes.
