Assertion (A) The denaturation of proteins can destroy all $1^{\circ}, 2^{\circ}$ and $3^{\circ}$ protein structures.

Reason (R) Curdling of milk is due to denaturation of proteins.

The correct option among the following is

154. Which of the following statements support the cyclic form for glucose?

(i) It doesn't give Schiff's test.

(ii) It is found to exist in two different crystalline forms.

(iii) It oxidises with nitric acid to give saccharic acid.

(iv) Pentaacetate of glucose doesn't react with hydroxylamine.

Considering the facts that

I. sucrose forms glycosidic linkage between $\mathrm{C}_1$ of glucose and $\mathrm{C}_2$ fructose, while

II. lactose forms glycosidic linkage between $\mathrm{C}_1$ of galactose and $\mathrm{C}_4$ of glucose.

Choose the correct statement.
