Best answer
Right choice is (a) barley starch

To explain: Maltose is produced from barley starch by treating it with barley β-amylases. Glucoamylases, papain and α-amylases are obtained from Aspergillus Niger, Carica papaya and Bacillus Licheniformis respectively. Papain is proteolytic enzyme that is used to tenderize meat. Glucoamylases cleaves α – 1,4 and α – 1,6 links to give β-glucose. α – amylase cleaves only a-1,4-oligosaccharide links are cleaved to give a-dextrin’s and predominantly maltose (G2), G3, G6 and G7 oligosaccharides.
