Raffinose is
A
A monosaccharide
B
A disaccharide
C
A tetrasaccharide
D
A trisaccharide
Explanation: 

Detailed explanation-1: -Raffinose is a trisaccharide in which glucose acts as a monosaccharide bridge between galactose and fructose. It has both and glycosidic bonds and can therefore be hydrolyzed to d-galactose and sucrose via enzymes with -glycosidic activity, and to melibiose and d-fructose via enzymes with -glycosidic activity.

Detailed explanation-2: -Since it contains 3 monosaccharide units, Raffinose is a trisaccharide. It provides glucose + fructose + galactose upon hydrolysis.

Detailed explanation-3: -The oligosaccharides consist of linkages of two or more molecules of monosaccharides. The major oligosaccharides include disaccharides (e.g., sucrose, maltose), trisaccharides (e.g., raffinose, melezitose), and tetrasaccharides (e.g., stachyose).

Detailed explanation-4: -Raffinose is a trisaccharide composed of galactose, glucose, and fructose. It can be found in beans, cabbage, brussels sprouts, broccoli, asparagus, other vegetables, and whole grains.

Detailed explanation-5: -Raffinose is trisaccharides containing three units of monosaccharides. It is composed of glucose, fructose, and galactose.
