The number of carbon atoms present in the given carbohydrates are as follows-

Hexose is a carbohydrate with six carbon atoms. Pentose has five carbon atoms. Tetrose has four carbon atoms. Triose has three carbon atoms.

Thus, a carbohydrate with five carbon atoms is called as Pentose.

B. pentose

pent = five

hex = six

tetra = four

tri = three

so the answer is pentose because it has 5 carbons
