A biological consequence of the extensive hydrogen bonding between cellulose chains in a microfibril is that the structure is

A. Highly flexible and elastic
B. Extremely rigid and possesses high tensile strength
✓
C. Soluble in aqueous buffers and readily degradable
D. Impermeable to all gases and water vapor

📝 Explanation

The regular, extensive inter-chain hydrogen bonds create a crystalline, paracrystalline array. This structure is what gives cotton, wood, and other cellulosic materials their remarkable tensile strength and rigidity, making cellulose an ideal structural molecule.
