(B) Lampbrush chromosomes are a special form of chromosome found in the growing oocytes (immature eggs) of most animals,except mammals. They are characterized by their large size and distinct 'lampbrush' appearance due to lateral loops of chromatin. The length of these chromosomes can be very significant,often reaching up to $1000 \ \mu m$ $(1 \ mm)$ or more in certain species like amphibians.
