Prions are abnormally shaped proteins that cause spongiform encephalopathies. (Ans C)
Explanation:
Prions : Prions are proteinaceous infectious particle or misfolded proteins with the ability to transmit their misfolded shape into normal shape protein. They are also responsible for some neurodegenerative diseases in mammals. They can affect both animals as well as humans.
Prion disease occurs when normal prion protein (present on the surface of many cells) becomes clump (abnormal) in the brain. This accumulation of abnormal protein in the brain can cause disease.
Spongiform encephalopathies also called prion disease. Spongiform encephalopathies affect the nervous system and brain of animals & humans. It is caused by a degeneration of brain tissues giving it a spongy appearance.

Answer:
option c is correct that is 32
Explanation:
meiosis occur in two phases in the first phase DNA replication occur and amount of DNA becomes doubled without any changes in the chromosomes number and two daughter cells( each 2n) are formed
now in stage 2 each daughter cell undergoes mitosis with the formation of two cells each with half chromosomes (n)
now 2n =32
n=32/2=16
after meiosis stage 1 ........ two daughter cell each with 32 chromosomes
stage 2.... each daughter cell form two grand daughter cell each with 16 chromosomes
