Identify the correct relationship between chromosomes and dna

The correct answer would be "chromosomes are the most condensed form of DNA".

DNA is present as chromatin fiber in the nucleus of the cell.

During cell division, the DNA or chromatin fiber gets condensed and converted into the structure termed as a chromosome.

Chromosome also contains few proteins which help in the condensation or packing of nucleic acid such as histone proteins.

DNA strand → Chromatin fiber (beads on a string) → 30 nm chromatin fiber → 300 nm chromatin fiber → chromosome

some fungi obtain their nutrients from a living host (plant or animal) and are called most biotrophic fungi have fairly narrow host ranges—they are specialized on a limited called rhizomorphs that allow the fungus to grow from one tree to another. ascospores are formed inside a sac-like structure called an ascus. so your answer is a
