The correct answer is 3) dead cells form a thick cheesy substance

Explanation:

Caseation necrosis refers to the necrosis which reflects the occurrence of the cell death where dead cell material shows the crumbly cheese like appearance. It usually occurs in lungs as well as kidneys. Example : tubercular infections. Main reason is caused by syphilis & fungi.
