Solution
The correct option is C Polytene chromosome
Polytene begins as normal chromosomes, but through repeated rounds of DNA replication without any cell division (called endoreplication). They become large, banded chromosomes and the resulting daughter chromatids do not separate but remain aligned side by side.The name polytene chromosome was proposed by Kollar due to the occurrence of many chromonemata (coiled filament in which the genes are located, which extends the entire length of a chromosome)So, the correct answer is 'Polytene chromosome'.
