The answer provided is incorrect.

Option 1 suggests both statements (A and R) are correct and R explains A. However, the reason that polysaccharides are not soluble in water does not explain why cellulose is used in making shatter-proof glass.

Option 2 also states both A and R are individually true, but R does not explain A. This is correct because while both statements are true, one does not explain the other. Cellulose, a polysaccharide, is used in making shatter-proof glass due to its strong fibrous nature which adds to the strength and flexibility of the glass, not because it`s insoluble in water.

Options 3 and 4 imply that either A or R is false, however both statements are individually true.

Alert - correct answer should be Option- 2 Both A and R are individually true R is not the correct explanation of A.
