Correct option is C)

Lampbrush chromosomes are mostly found in growing oocytes of most animals, except mammals. The shape is attained due to an active transcription of many genes during diplotene stages. They are highly extended meiotic half-bivalents, each consisting of 2 sister chromatids.
So, the correct answer is option C.
