At the subcellular level, starch is stored in amyloplasts in the endosperm of cereals. Two enzymes responsible for initiating starch degradation are α- and β-amylase

a) α-Amylase hydrolyzes starch chains internally to produce oligosaccharides consisting of α(1,4)-linked glucose residues

b) β-Amylase degrades these oligosaccharides from the ends to produce maltose, a disaccharide

c) α-Amylase degrades these oligosaccharides from the ends to produce maltose, a disaccharide

d)  α-Amylase hydrolyzes starch chains internally to produce oligosaccharides consisting of  β(1,4)-linked glucose residues

e) β-Amylase also converts maltose to glucose

Which of the following combination from the above statements is correct?
