The correct statement about chromosomes is:
**B. chromosomes contain DNA.**
Chromosomes are structures within cells that are made up of DNA and proteins. They carry genetic information.
To clarify the other statements:
- **A** is false because haploid cells (gametes) have half the number of chromosomes compared to diploid body cells.
- **C** contains an error as it is repeated as D; chromosomes are typically found in pairs (diploid) or single sets (haploid) in organisms, not in sets of three.
- **D** is false because DNA is contained within chromosomes, not the other way around.
So, **B** is the only true statement.
