Does the main fermentation of beer include malting roasting milling saccharification steaming

Including. According to the brewery quality control standard department requirements show that the industrial production process of beer: germination → roasting → milling → saccharification → steaming → fermentation → disinfection → termination. Roasting kills the embryo of barley seeds, but does not inactivate amylase, A is wrong; saccharification process amylase breaks down starch into syrup, B is correct; steaming kills microorganisms in the syrup and avoids contamination by stray bacteria.
