Solution
The correct option is D Polytene chromosomes - Oocytes of amphibians
Polytene chromosomes are giant chromosomes are a result of repeated rounds of DNA replication without undergoing cell division. Polytene chromosomes are found in Drosophila flies. They are not found in oocytes of amphibians.
Lampbrush chromosomes are formed during diplotene stage of meiotic prophase I. They are bivalent, which means it is made up of two homologous chromosomes paired together. It is a special type of chromosomes that are found in the immature eggs of many animals like amphibian oocytes but not in mammals.
Submetacentric chromosomes are those whose centromere is present slightly off-centre. As a result, they have 1 arm short and 1 arm long. So they look L-shaped sometimes.
Allosomes are sex chromosomes, in humans there are two types; X and Y chromosomes.
