Expert Answer

Step 1

A furanose is a five membered ring system. A furanose ring contain four carbon atom and one oxygen atom. A pyranose is a six membered ring system. Pyranose ring contain five carbon atom and one oxygen atom.

Step 2

The structure given in option “a” consist a ring that have four carbon atom and one oxygen atom that is five memberd ring . Thus, the structure given in option “a” contain a furanose ring.

Step 3

The structure given in option “b” consist a ring that have five carbon atom and one oxygen atom that is...
