Answer:
D. the homologous chromosomes are paired AND the spindle is formed
Explanation:
Meiosis is the type of cell division that results in four daughter cells with each having a reduced number of chromosomes (by half). Both meiosis and mitosis occur in different stages including prophase, metaphase, anaphase etc but meiosis occurs in two series of division processes called meiosis I and meiosis II.
In prophase I of meiosis, homologous chromosomes, which are similar but non-identical chromosomes from male and female parents pair to form tetrad or bivalent. This pairing of homologous chromosome is unique and peculiar to MEIOSIS but never mitosis.
They are usually held out for a period of FOUR TO SIX WEEKS after diagnosis. Splenomegaly is an infectious disease that corrupt the spleen and the enlarged spleen usually persist even after all the symptoms have disappeared. Because of this, athletes should not resume active exercise too soon. Generally, the shortest period after which it is okay to resume active exercise is four weeks after all the symptoms have gone.

Eukaryotic cells contain membrane-bound organelles, including a nucleus. Eukaryotes can be single-celled or multi-celled, such as you, me, plants, fungi, and insects. Bacteria are an example of prokaryotes. Prokaryotic cells do not contain a nucleus or any other membrane-bound organelle.
There are several key differences between prokaryotic and eukaryotic cells. Eukaryotic cells are found in multicellular plants and animals, whereas prokaryotic cells are found in bacteria and archaea which are ususlly unicellular. I have summarised the key differences below:
Prokayotic cells do not have membrane-bound organelles, such as the endoplasmic reticulum or mitochondria.
Prokaryotic cells do not have a nucleus, instead they have circular DNA that is free in the cytoplasm.
Prokaryotic cells have smaller ribosomes than eukaryotic cells.
Prokaryotic cells have a cell wall. Their cell wall is made from a different material to a plant cell, a glycoprotein called murein.
Prokaryotic cells may also have a protective layer called a capsule, flagellum to aid in movement and one or more plasmids.
