Statement (a) is correct. Allose is a hexose. It has 4 chiral centres. Therefore, the number of isomers of allose are 2n = 24 = 16.
Statement (c) is correct. Trehalose is a disaccharide formed by 1-1 glycosidic bond between the two alpha glucose units. Therefore in trehalose, anomeric carbon of both glucose are involved in glycosidic linkage so it is a non-reducing sugar and also does not exhibit mutarotation.
Statement (d) is incorrect
α.D glucose and β D glucose are anomers. Isomeric forms of monosaccharides that differ only in their configuration about the hemiacetal or hemiketal carbon atoms are called anomers. D glucose and D galactose are C-4 epimers.
Two sugars that differ only in the configuration around one carbon atom are called epimers. D galactose differs from D glucose in the configuration around 4th carbon atom.
Statement (c) is correct. Trehalose is a disaccharide formed by 1-1 glycosidic bond between the two alpha glucose units. Therefore in trehalose, anomeric carbon of both glucose are involved in glycosidic linkage so it is a non-reducing sugar and also does not exhibit mutarotation.
Statement (d) is incorrect
α.D glucose and β D glucose are anomers. Isomeric forms of monosaccharides that differ only in their configuration about the hemiacetal or hemiketal carbon atoms are called anomers. D glucose and D galactose are C-4 epimers.
Two sugars that differ only in the configuration around one carbon atom are called epimers. D galactose differs from D glucose in the configuration around 4th carbon atom.

All of the statements are true.
a) Maximum possible isomers of allose are 16: This statement is true. Allose is a monosaccharide with 5 carbon atoms, and each carbon atom can have a different configuration (D or L). Therefore, there are 2^5 = 32 possible isomers. However, half of these isomers are identical due to symmetry, so the maximum possible isomers of allose are 16.
b) Glycogen has several non-reducing ends but only one reducing end: This statement is true. Glycogen is a polysaccharide composed of glucose units linked together. It has multiple branches, resulting in several non-reducing ends. However, it has only one reducing end, which is the end of the glycogen molecule where a new glucose unit can be added or removed.
c) Trehalose does not exhibit mutarotation: This statement is true. Mutarotation is the process in which the specific rotation of a sugar solution changes over time due to the interconversion of its anomeric forms (alpha and beta). Trehalose, a disaccharide composed of two glucose units, does not exhibit mutarotation because it does not have a free anomeric carbon that can undergo interconversion.
d) Maltose is a reducing sugar: This statement is true. Maltose is a disaccharide composed of two glucose units linked by an alpha-1,4-glycosidic bond. It has a free anomeric carbon at the reducing end, which can reduce other substances, such as Fehling's solution or Benedict's solution. Therefore, maltose is considered a reducing sugar.
