(D) Polytene chromosomes are giant chromosomes formed by the process of endoreduplication or endomitosis.In this process,the $DNA$ undergoes repeated rounds of replication without the subsequent division of the cell or the nucleus.This results in the formation of many parallel chromatids (strands) within a single chromosome,which is why they are called polytene (many-stranded).Since endoduplication,duplication without separation,and replication of $DNA$ without cell division describe the same phenomenon,all the given options are correct.

Polytene chromosomes in salivary glands are formed as a result of:
