Final answer:
Creutzfeldt Jakob Disease (CJD) is likely caused by a prion and can spread through the consumption of infected brain tissue, leading to spongiform degeneration of brain tissue. Option b.
Step-by-step explanation:
The disease that is probably caused by a prion is Creutzfeldt Jakob Disease (CJD). Prions are abnormal pathogenic agents that are responsible for transmitting neurodegenerative diseases. Unlike other infectious agents, prions contain no genetic material and are composed solely of a specific type of abnormally folded protein. One way CJD has been documented to spread from human to human is through the consumption of infected brain tissue, typically through meats contaminated with central nervous system tissue.
The PrPSC is the disease-causing form of the prion that causes the normal prion protein to also misfold, leading to brain damage and rapid degeneration of brain tissue, presenting spongiform changes or holes in the brain tissue.
