Lampbrush chromosomes are also called diplotene chromosomes because they are formed during the diplotene stage of prophase1 of meiosis cell division due to the active transcription of many genes.
These chromosomes are seen during the early prophase stage and are bivalent having two conjugating homologues joined at chiasmata.
They are a special type of chromosome found in the developing oocytes of most animals (except mammals).
So, the correct answer is 'All of the above'.
