DNA (deoxyribonucleic acid) is indeed known for its crucial role in carrying genetic information in all living organisms, which makes the statement about it correct. DNA contains the instructions needed for an organism's growth, development, functioning, and reproduction. This hereditary material is found in both prokaryotic and eukaryotic cells, providing a universal blueprint for life. The genetic code stored within DNA is transcribed into RNA and then translated into proteins, which perform the majority of functions in a cell.

The other statements do not hold true: DNA is not exclusive to eukaryotic cells, as prokaryotic cells (like bacteria) also contain DNA. DNA itself does not directly produce energy; that process is primarily the function of cellular structures like mitochondria in eukaryotes, where energy is generated via cellular respiration. Additionally, while DNA plays a significant role in determining the processes involved in cellular respiration, it is not solely responsible for it; many proteins and enzymes, coded by DNA, are involved in the respiration process alongside various metabolic pathways. Thus, the statement regarding DNA carrying genetic information is the most accurate and comprehensive.
