Consider the following.

Statement I : Lactose is composed of $\alpha$ - $D$-glucose and $\beta$-D-glucose.

Statement II : Lactose is a reducing sugar.

$$ \text { Match the following. } $$

$$ \text { The synthetic detergents of the following are } $$

B. $\mathrm{CH}_3\left(\mathrm{CH}_2\right)_{10} \mathrm{CH}_2 \mathrm{OSO}_3 \mathrm{Na}$

C. $\mathrm{CH}_3\left(\mathrm{CH}_2\right)_{15} \mathrm{~N}\left(\mathrm{CH}_3\right)_3 \mathrm{Br}$

D. $\left(\mathrm{C}_1 \mathrm{H}_{31} \mathrm{COO}\right)_3 \mathrm{C}_3 \mathrm{H}_5$

Correct answer is

$$ \text { In the given reaction sequence conversion of } Y \text { to } Z \text { is } $$
